Previously only editor+ roles could manage recipes, so viewer users
saw an empty "我的配方" section. Now any authenticated user can CRUD
their own recipes while admin/senior_editor retain full access.

FastAPI's StaticFiles only served index.html for /. Now all non-API,
non-asset routes return index.html so Vue Router handles client-side routing.
