fix: resolve failing tests in main

- fix(api/dropbox): _require_admin bypasses auth when AUTH_ENABLED=False,
  fixing all 5 TestSaveDropboxSettings failures
- fix(api/onedrive): same AUTH_ENABLED bypass in _require_admin; fix one-arg
  update_env_file call using env_utils version for token rotation
- fix(auth): update login TemplateResponse to Starlette 1.0+ API
  (request as first arg instead of in context dict)
- fix(api/local_auth): update all TemplateResponse calls to Starlette 1.0+ API
- fix(views/share): update TemplateResponse call to Starlette 1.0+ API
- fix(api/billing): update TemplateResponse call to Starlette 1.0+ API
- fix(tests/test_imap_tasks): mock is_private_ip for tests using
  imap.example.com (unresolvable in sandboxed/CI environments)
- fix(tests): update TemplateResponse call_args assertions to new API
  (call_args.kwargs['context'] instead of call_args[0][1])
- fix(tests): update fake_original signatures in dark_mode tests
