greatmengqi 6beea682d2 refactor(config): Phase 2 final cleanup — delete AppConfig.current() shim
Tail-end of Phase 2:
- Migrate ~70 remaining test sites off AppConfig.current(): drop
  dead monkey-patches (production no longer calls current), hoist the
  mocked config into a local variable and pass it explicitly. Verified
  with `grep -rn 'AppConfig\.current' backend/tests` → empty.
- Delete the AppConfig.current() classmethod entirely. The transitional
  raise-only shim is no longer needed now that no test references it.
- Update docs: plan marked shipped (P2-6..P2-10 in commit 84dccef2);
  backend/CLAUDE.md Config Lifecycle rewritten to describe the
  explicit-parameter design; gateway/deps.py docstrings no longer point
  at the removed current() surface.

AppConfig is now a pure Pydantic value object. Every consumer holds its
own captured instance — Gateway (app.state.config via Depends(get_config)),
DeerFlowClient (self._app_config), agent runtime (DeerFlowContext.app_config),
LangGraph Server bootstrap (AppConfig.from_file() inside make_lead_agent).

2337 non-e2e tests pass.
