* Add bytes stored per type to org and metrics
The org now tracks bytesStored by type of crawl, uploads, and browser profiles
in addition to the total, and returns these values in the org metrics endpoint.
A migration is added to precompute these values in existing deployments.
In addition, all /metrics storage values are now returned solely as bytes, as
the GB form wasn't being used in the frontend and is unnecessary.
* Improve deletion of multiple archived item types via `/all-crawls` delete endpoint
- Update `/all-crawls` delete test to check that org and workflow size values
are correct following deletion.
- Fix bug where it was always assumed only one crawl was deleted per cid
and size was not tracked per cid
- Add type check within delete_crawls
