Add SessionData.needsVerification field (#2672)

* Add `SessionData.needsVerification`:
  - Allows us to add a skip button for debug builds.
  - We can have the verification state almost instantly.
  - It doesn't depend on network availability to know the verification state and display the UI.
* Add DB migration.
- Make the skip button in the verification flow skip the whole flow including the completed screen.
- Save the session as verified in `RustEncryptionService.recover(recoveryKey)`.
* Enforce session verification for existing users too.
* Fix verification confirmed screen subtitle (typo in id, was using the wrong string)
* Update screenshots
