This PR replaces the APScheduler lib with the Taskiq task queuing lib.
# why
APScheduler doesn't support FastAPI's DI in tasks, this makes them quite
cumbersome to read and write since DB, Repositories and Services all
need to be instanciated manually.
Moreover, Taskiq makes it easier to start background tasks from FastAPI
requests. This enables MM to move to a more event-based architecture.

## Summary by CodeRabbit
* **New Features**
* App now uses an orchestrated async startup/shutdown and runs
background scheduling via a database-backed task queue; startup enqueues
pre-load/import/update tasks.
* **Bug Fixes**
* Improved torrent client handling with clearer conflict messages and
guidance for manual resolution.
* Enhanced logging around season, episode and metadata update
operations; minor regex/behaviour formatting preserved.
* **Chores**
* Updated dependencies to support the new task queue and connection
pooling.
