- Renamed models, migration files, and database tables for greater consistency (e.g., `service_protocols` to `connection_protocols`, `service_providers` to `connection_providers`).
- Enabled `SoftDeletes` trait on core models, including `User`, `ConnectionProvider`, `ConnectedApp`, and others.
- Updated migration schemas to include `softDeletes()` and adjusted `down()` methods accordingly.
- Enhanced indexing in `connected_apps` to optimize query performance.
