Upload Fixes: (#2397)
- ensure upload pages are always added with a new uuid, to avoid any
duplicates with existing uploads, even if upload wacz is actually a
crawl from different browsertrix instance, etc..
- cleanup upload names with slugify, which also replaces spaces, fixes
uploading wacz filenames with spaces in them
- part of fix for #2396

Add support for custom link selectors to backend (#2346)
Related to #2152 

This PR adds backend support for custom link selectors via `selectLinks`
on the crawl workflow config. Tests have been updated as well.

It also adds `selectLinks` to the frontend in a minimal and for now
hardcoded way that we can use as a basis for proper frontend support
moving forward.

Mark all pages from pages.jsonl as seeds (#2390)
Fixes #2389 

All pages from `pages/pages.jsonl` files now have `isSeed: True` in the
database, in addition to any pages that explicitly have `seed` set to
true in the actual JSONL.

Tests have been added to ensure that all pages from our fixture uploads
have `isSeed: True`.

Add collection page list/search endpoint (#2354)
Fixes #2353

Adds a new endpoint to list pages in a collection, with filtering
available on `url` (exact match), `ts`, `urlPrefix`, `isSeed`, and
`depth`, as well as accompanying tests. Additional sort options have
been added as well.

These same filters and sort options have also been added to the crawl
pages endpoint.

Also fixes an issue where `isSeed` wasn't being set in the database when
false but only added on serialization, which was preventing filtering
from working as expected.

Fix max pages quota setting and display (#2370)
- add ensure_page_limit_quotas() which sets the config limit to the max

- set the page limit on the config when: creating new crawl, creating
configmap
- don't set the quota page limit on new or existing crawl workflows
(remove setting it on new workflows) to allow updated quotas to take
affect for next crawl
- frontend: correctly display page limit on workflow settings page from

Fix migration to avoid duplicate collection slugs and names (#2318)
Follow-up to #2301 

Updates the 0039 migration to ensure collection slugs and names are
unique by:
- Removing all indexes
- Setting `slug` to random value
- Adding unique index to `slug` field.
- Attempting to set slug from name using `slug_from_name()`
- If rejected due to duplicate, append `-<counter>` at end of slug. Also
update name with ` <counter>`.
- Now that names should also be unique, add unique index on name field.

Add pageCount to crawls and uploads and use in frontend for page counts (#2315)
Fixes #2257 

This is a follow-up to the public collections work, which adds pages to
the database for uploads. All crawls and uploads now have a `pageCount`
field which is populated when the item is successfully added. A new
migration is also added to populate the field for existing archived
items that don't have it set yet.

OrgMetrics have also been modified to include `crawlPageCount` and
`uploadPageCount`, and to include the total of both in `pageCount`, and
all three included in the frontend org dashboard.

The frontend has been updated to use `pageCount` rather than
`stats.done` wherever appropriate, meaning that in archived item lists
and details we now have a consistent page count for both crawls and
uploads.

### New functionality

- Deploy this branch
- Create new crawls and uploads and verify that page count appears
correctly throughout the frontend for all new crawls and uploads

### Migration

- Deploy from latest main
- Create some crawls and uploads
- Change to this branch and re-deploy
- Verify migration ran without errors in backend logs
- Verify that page count has been populated successfully by checking
archived items lists, crawl and upload detail pages, and dashboard to
ensure there are no longer any missing page counts.

Add support for autoclick (#2313)
Fixes #2259 

This PR brings backend and frontend support for the new autoclick
behavior in Browsertrix, introduces in Browsertrix 1.5.0+

On the backend, we introduce `min_autoclick_crawler_image` to
`values.yaml`, with a default value of
`"docker.io/webrecorder/browsertrix-crawler:1.5.0"`. If this is set and
the crawler version for a new crawl is less than this value, the
autoclick behavior is removed from the behaviors list in the configmap
created for the crawl.

The one caveat for this is that a crawler image tag like "latest" will
always be parsed as greater than `min_autoclick_crawler_image`, so there
is the potential for the crawler to run into issues if using a
non-numeric image tag with an older version of the crawler. For
production we use hardcoded specific versions of the crawler except for
the dev channel, which from here on out will including autoclick
support, so I think this should be okay (and is also true of the
existing implementation for checking `min_qa_crawler_image`).

On the frontend, I've added a checkbox (unchecked by default) in the
"Limits" section just below the current checkbox for autoscroll. We
might want to move these to a different section eventually - I'm not
sure Limits is the right place for them - but I wanted to be consistent
with things as they are.

Backend work for public collections (#2198)
Fixes #2182 

This rather large PR adds the rest of what should be needed for public
collections work in the frontend.

New API endpoints include:

- Public collections endpoints: GET, streaming download
- Paginated list of URLs in collection with snapshot (page) info for
each
- Collection endpoint to set home URL
- Collection endpoint to upload thumbnail as stream
- DELETE endpoint to remove collection thumbnail

Changes to existing API endpoints include:

- Paginating public collection list results
- Several `pages` endpoints that previously only supported `/crawls/` in
their path, e.g. `/orgs/{oid}/crawls/all/pages/reAdd`, now support
`/uploads/` and `/all-crawls/` namespaces as well. This is necessitated
by adding pages for uploads to the database (see below). For
`/orgs/{oid}/namespace/all/pages/reAdd`, `crawls` or `uploads` will
serve as a filter to only affect crawls of that given type. Other
endpoints are more liberal at this point, and will perform the same
action regardless of the namespace used in the route (we'll likely want
to change this in a follow-up to be more consistent).
- `/orgs/{oid}/namespace/all/pages/reAdd` now kicks off a background job
rather than doing all of the computation in an asyncio task in the
backend container. The background job additionally updates collection
date ranges, page/size counts, and tags for each collection in the org
after pages have been (re)added.

Other big changes:

- New uploads will now have their pages read into the database!
Collection page counts now also include uploads
- A migration was added to start a background job for each org that will
add the pages for previously-uploaded WACZ files to the database and
update collections accordingly
- Adds a new `ImageFile` subclass of `BaseFile` for thumbnails that we
can use for other user-uploaded image files moving forward, with
separate output models for authenticated and public endpoints

Add public API endpoint for public collections (#2174)
Fixes #1051 

If org with provided slug doesn't exist or no public collections exist
for that org, return same 404 response with a detail of
"public_profile_not_found" to prevent people from using public endpoint
to determine whether an org exists.

Endpoint is `GET /api/public-collections/<org-slug>` (no auth needed) to
avoid collisions with existing org and collection endpoints.

Optionally delay replica deletion (#2252)
Fixes #2170

The number of days to delay file replication deletion by is configurable
in the Helm chart with `replica_deletion_delay_days` (set by default to
7 days in `values.yaml` to encourage good practice, though we could
change this).

When `replica_deletion_delay_days` is set to an int above 0, when a
delete replica job would otherwise be started as a Kubernetes Job,
a CronJob is created instead with a cron schedule set to run yearly,
starting x days from the current moment. This cronjob is then deleted by
the operator after the job successfully completes. If a failed
background job is retried, it is re-run immediately as a Job rather
than being scheduled out into the future again.

Allow configuring available languages from helm chart (#2230)
Closes #2223 

- [x] Adds `localesAvailable` to `/api/settings` endpoint, and uses that
list if available, rather than the full list of translated locales, to
determine which options to display to users
- [x] ~~Uses the user's browser locales, filtered to the current
language setting, for formatting numbers, dates, and durations~~
- [x] Adds & persists checkbox for "use same language for formatting
dates and numbers" in user settings
- [x] Replaces uses of `sl-format-bytes` with `localize.bytes(...)`, and
`sl-format-date` with replacement `btrix-format-date` that properly
handles fallback locales
- [x] Caches all number/duration/datetime formatters by a combined key
consisting of app language, browser language, browser setting, and
formatter options so that all formatters can be reused if needed
(previously any formatter with non-default options would be recreated
every render)
- [x] Splits out ordinal formatting from number formatter, as it didn't
make much sense in some non-English locales
- [x] Adds a little demo of date/time/duration/number formatting so you
can see what effect your language settings have

Send subscription cancelation email (#2234)
Adds sending a cancellation email when a subscription is cancelled.
- The email may also include an option survey optional survey URL, if
configured in helm chart `survey_url` setting.
- Cancellation e-mail configured in `sub_cancel` e-mail template
- E-mails are sent to all org admins.
- Also adds `trialing_canceled` subscription state to differentiate from
a default `trialing` which will automatically rollover into `active`.
- The email is sent when: a new cancellation date is added for an
`active` subscription, or a `trialing` subscription is changed to to
`trialing_canceled`. (A subscription can be canceled/uncanceled several
times before actual date, and e-mail is sent every time it is canceled.)
- The 'You have X days left of your trial' is also always displayed when
state is in trialing_canceled.
