[web] Restore compaction

Summary:
Restore compaction on web. Because web keeps redux persist storage in the database, and native doesn't, we must also:

• save redux persist date before restoration
• put it back after it's restored

We can do that before applying logs, before we can be sure that they won't touch this table.

Moved a few persist constants to a new file because otherwise webworker imported something that used window, which isn't available there.

Depends on D11042

Test Plan:

• Add logging to the native client so that it logs backupID and encryption keys for compaction
• Upload a new compaction from native with a draft
• Send restore message
• Reload web app
• Check that the draft from native exists now on web. Check that the enabled apps are the same as before restore (redux persist didn't change)
