Epic Index: Turn Tessa into a client-side only gem & decomission Tessa service

[gburgett]

The Tessa service was very useful back in the days before ActiveStorage, but now ActiveStorage is the Rails best practice way to do things and comes batteries-included with Rails 7.

Rework the Tessa gem so that it no longer uploads to the Tessa service, but rather uploads/downloads directly to s3 via ActiveStorage. Clients would no longer have Tessa username/password credentials, but rather AWS s3 access credentials.

Then kill the Tessa app in Heroku.

• 1. Rework the Tessa gem so that it acts as a wrapper around ActiveStorage for new uploads, w/ fallback to the Tessa service for missing images.

  • Gem: Rework as a wrapper around ActiveStorage tessa-client#15
  • Events system: https://github.com/watermarkchurch/events/issues/459
  • Media System https://github.com/watermarkchurch/media/issues/489
  • Watermark Resources https://github.com/watermarkchurch/watermarkresources.com/issues/1636
  • JTJ-CMS https://github.com/watermarkchurch/jtj-cms/issues/455

• 2. Run a migration in an ActiveRecord job on each downstream client app that creates ActiveStorage records in the client app's Postgres for all old tessa uploads

  • Events System: https://github.com/watermarkchurch/events/issues/460
  • Media System this is unnecessary
  • Watermark Resources https://github.com/watermarkchurch/watermarkresources.com/issues/1702
  • JTJ-CMS https://github.com/watermarkchurch/jtj-cms/issues/470

• 3. Remove fallback to Tessa service (perhaps by just removing the TESSA_URL env var?) and test that all old assets still resolve

  • Events System https://github.com/watermarkchurch/events/issues/562
  • Media System https://github.com/watermarkchurch/media/issues/527
  • Watermark Resources https://github.com/watermarkchurch/watermarkresources.com/issues/1719
  • JTJ-CMS https://zube.io/watermarkchurch/development/c/12438
  • Gem: Remove fallback code to Tessa service tessa-client#16

• 4. Decommision Tessa

  • Turn off the Tessa service Turn off the tessa service #49
  • Archive and decommission the Tessa repo Archive Tessa application #50

• 5. Cleanup

  • Clean up old tessa assets (Clean up old tessa assets #51)
  • Remove duplicate assets from media-files.watermark.org (https://github.com/watermarkchurch/media/issues/539)

Could we potentially consider using something like cloudinary instead?

Cloudinary would be great as a backend to ActiveStorage. I'd like to move this as close to the "official path" for Rails apps as possible.
