feat: remove proto files and related gRPC code

- Deleted the generated proto file `sovrabase.proto` and its corresponding Go files `sovrabase.pb.go` and `sovrabase_grpc.pb.go`.
- Removed the test script `test_orchestrator_api.go` and added a new configuration file `config.yaml` for orchestrator settings.
- Introduced CORS middleware in `internal/middleware/cors.go` with comprehensive tests in `internal/middleware/cors_test.go`.
- Updated orchestrator tests in `internal/orchestrator/test_orchestrator_api.go` to ensure proper database lifecycle management.
