[Config] Implement configuration synchronization between file and database (fixes #3013)

[adityajha2005]

Description

• This PR implements a configuration synchronization system that ensures consistency between the file-based configuration (db.config.json) and the database configuration.

The implementation follows these requirements:

1. On startup, the file configuration is read and used to update the database configuration
2. On shutdown, the database configuration is read and used to update the file configuration
3. All configuration changes made in tasks or gunicorn processes are made to the database
4. All configuration reads are from the config file

This ensures configuration changes made during runtime are preserved in the file for the next startup while maintaining the file as the source of truth for reading configuration values.

This PR fixes #3013

Notes for Reviewers

• A new module augur/application/config_sync.py was created to handle the synchronization logic
• The API, collection, and tasks CLI modules were modified to call the synchronization functions on startup and shutdown
• The database engine and facade worker were updated to always read configuration from the file
• Tests were added to verify the synchronization functionality
