feat(admin-v2): add ProTable search, scenarios/quick_commands form, tests, remove quota_reset_interval

- Enable ProTable search on Accounts (username/email), Models (model_id/alias),
  Providers (display_name/name) with hideInSearch for non-searchable columns
- Add scenarios (Select tags) and quick_commands (Form.List) to AgentTemplates
  create form, plus service type updates
- Remove unused quota_reset_interval from ProviderKey model, key_pool SQL,
  handlers, and frontend types; add migration + bump schema to v11
- Add Vitest config, test setup, request interceptor tests (7 cases),
  authStore tests (8 cases) — all 15 passing
