Implement BitDepth Management with CRUD Operations

- Add `BitDepth` entity with JPA annotations and database mapping.
- Create repository, service, and delegate handlers for BitDepth CRUD operations: `bitdepth.create`, `bitdepth.getAll`, `bitdepth.getById`, `bitdepth.update`, `bitdepth.delete`.
- Introduce Protobuf definitions for BitDepth messages.
- Register BitDepth service and handlers in `DelegateActionManager`.
- Create `BitDepthMapper` to map between Protobuf and entity models.
- Enhance error handling and logging for BitDepth operations.
