refactor(mobile): DB repository for asset, backup, sync service

[fyfrey]

This PR removes the direct dependency on Isar for the last services: asset, backup and most difficult sync.
To do so, this PR introduces new methods to existing database repositories.

Now, only providers are left to refactor to use the services (or repositories) instead of directly performing database operations.

LGTM. Hopefully we're at a point where we can add more unit tests now.

Hello Fynn, thank you for the PR. Below are some results of my testing

Assertion trigger 🟠

When first signing in an instance, I am seeing this assertion gets triggered, even signing out and singing back in trigger this condition.

flutter: FlutterError - Catch all: 'package:immich_mobile/services/sync.service.dart': Failed assertion: line 141 pos 12: 'dbUsers.isSortedBy((u) => u.id)': dbUsers not sorted!

Asset sync 🟢

After commenting out the assertion condition, the sync process was completed successfully to get all current and partner users' assets.

Album sync 🟢

Album sync also works correctly.

[alextran1502]

Should we invalidate this in invalidateAllApiRepositoryProviders() as well?

[alextran1502]

What is this for?

[alextran1502]

In the upcoming layout, I will need to get all albums, both shared and owned. Can it be done with this interface in a single invocation?
