Fix MongoDB database selection - use database from connection string

- Extract database name from MONGO_URI connection string if present
- Fallback to 'object_remover' only if no database in connection string
- Add detailed logging showing which database is being used
- This ensures logs are stored in the correct database specified in MONGO_URI
