✨ (expo) Ephemeral reading timer and improved conflict resolution

[aaronleopold]

Description

This branch started with ephemeral reading timer refactors to improve some drift/funk between online/offline reading, and morphed to also build out more advanced conflict resolution when syncing offline progress to your Stump server:

• Remove extra locally-persisted reading times (zustand), seconds are now source from either
  • local sqlite database for offline reading
  • a remote Stump server
• Consolidate common timer ops into useReadingTimer
• Add ability to reset timer for both online/offline reading
• Add explicit CONFLICT status so conflicts can be manually managed after detected during sync operations
• Add a conflict-resolution sheet with a pager view to manually resolve conflicts sequentially with multiple options:
  • Accept local -> your local progression will replace any remote progress at the divergence point
  • Accept remote -> your remote progression will replace your local progress
  • Accept both -> your local progression will be appended to your remote progress as a continuation
• Add the concept of a ReadingSessionConflictResolutionView
• Adjust server mutations to better support timer resets atomically within a single transaction, instead of serially calling clear then update progress
  • Refactor some bits into reusable service functions
  • Add corresponding tests, etc
• Add initial helpers for querying a Stump server outside server context, will be more common moving forward so will want to improve these patterns
• ... And a bunch more

There are still some remaining TODOs sprinkled throughout I'll need to address, but think this is getting close to ready. I'm hoping to wrap it up within a week's time.

TODO: I will add later
