fix: add /search alias so external clients don't get 404

- Vite dev server: proxy /search to backend with path rewrite to /api/search
- FastAPI: add GET+POST /search route that 307-redirects to /api/search
  (307 preserves the original HTTP method, so POST stays POST)
- Fixes 404 for clients calling /search instead of /api/search
