feat: Add migration init container to StatefulSet

Browse source 
- Add migration init container that runs before main app containers
- Ensures database migrations are applied on every deployment
- Includes all necessary environment variables for migration execution
- Disable AUTO_MIGRATE in main container since init container handles it
- Prevents race conditions by running migrations before cluster formation

This resolves issues where migrations weren't running in cluster mode
and ensures new deployments always have the latest schema changes.
