Remove unused imports and tidy auth imports

Remove unused typing imports (Union and Optional) and clean up import ordering/whitespace. In src/api/auth.py move logging/telemetry/version imports and logger initialization to group related imports, and remove an unused Optional import in workspace_config_repo.py. Small refactor to reduce lint warnings and improve import organization.
