feat: add client history and subtypes

- Added subtypes for services (Service/Retouch).
- Implemented expandable client rows to show service history.
- Added a search bar to filter clients by name.
- Added 'Oncological' status column to the client list.
- Created a new API endpoint for client history.

fix(db): ensure database persistence in Docker
- The database path is now configurable via the DB_PATH environment variable.
- The Dockerfile has been updated to create a persistent volume for data.
- The README now contains the correct 'docker run' command for data persistence.
