Scheduler used a separate SQLite file (scheduler.db) only to persist one
cron job. This was originally required because APScheduler's
SQLAlchemyJobStore is sync-only, creating an async/sync driver conflict
when accessing the same file.
The job is rebuilt from config.json on every startup regardless
(replace_existing=True), so the persisted state only served misfire
detection. Moved misfire detection into the app layer by querying
system_settings.last_scan_timestamp on startup: if the last scan is
>23h but <25h ago, an immediate rescan is triggered.
Change summary:
- Remove SQLAlchemyJobStore; use default MemoryJobStore instead
- Add _check_missed_run() that reads last_scan_timestamp from aniworld.db
- Update docs/DEVELOPMENT.md scheduler troubleshooting section
- Update the scheduler unit test that verified SQLAlchemyJobStore
