Fix ingest system: Refresh database session after book imports

- Resolves issue where multiple books don't appear until container restart
- Adds automatic session refresh after each successful calibredb import
- Uses existing TaskReconnectDatabase infrastructure for safe refresh
- Maintains fault tolerance - continues processing if refresh fails
- Books now appear immediately in CWA UI without restart

Fixes database session isolation between external calibredb adds and
CWA's SQLAlchemy session cache.
