- Fix Ctrl-C shutdown by using fx.Shutdowner instead of just canceling context
- Pass context from fx lifecycle to rw.Run() for proper cancellation
- Adjust WAL settings: checkpoint at 50MB, max size 100MB
- Reduce busy timeout from 30s to 2s to fail fast on lock contention
This should fix the issue where Ctrl-C doesn't cause shutdown and improve
database responsiveness under heavy load.

- Increase SQLite connection pool from 1 to 10 connections for better concurrency
- Optimize SQLite pragmas for balanced performance and safety

- Update all constructors and dependencies to use the new logger
- Increase batch size from 100/50 to 500 for both handlers
