Phase 2 Task P2-1: introduce the explicit-config primitive used throughout the rest of Phase 2. FastAPI routers will migrate from AppConfig.current() to `config: AppConfig = Depends(get_config)` reading from app.state.config. This commit only adds the new path. AppConfig.init() remains alongside so unmigrated call sites still work; it is removed in P2-10 once every caller is migrated.

"""Tests for the FastAPI get_config dependency.

Phase 2 step 1: introduces the new explicit-config primitive that
|
|
resolves ``AppConfig`` from ``request.app.state.config``. This coexists
|
|
with the existing ``AppConfig.current()`` process-global during the
|
|
migration; it becomes the sole mechanism after Phase 2 task P2-10.
