Fixes https://github.com/webrecorder/browsertrix/issues/2595
## Changes
Adds "Subscription Cancellation Scheduled" state/icon/tooltip to
superadmin org list, with future cancellation duration/date.
Adds more subscription-related info and features to the action menu in
the same org list
- "Open in Stripe" action is visible if subscription id is a Stripe
object id
- "Plan ID" and "Action on Cancel" correspond to `planId` and
`readOnlyOnCancel` properties on `subscription` object
- There's also some additional highlighting for possible errors
(hopefully only visible on dev) — see the last screenshot for an example
Adds first pass at filters for superadmin org list
- The filters' counts update when searching
- I took an initial pass at figuring out which filters would be most
useful — we can always go back and tweak them later
