The Places API googleMapsUri is a cid-style URL with no ftid, so the
search/getPlaceDetails fixtures had stored a fabricated ftid. Switch them
to real cid URLs and assert google_ftid is null — the precise
query_place_id link still fixes the wrong-spot bug — and document the
behaviour on googleFtidFromMapsUrl.
- add a direct googleFtidFromMapsUrl test: extracts a real /place ftid,
returns null for a cid URL, rejects malformed/hostile values
- add placeGoogleMaps.test.ts covering the whole fallback chain
(ftid -> place_id -> details URL -> coords) and the hostile-ftid rejection
- PlaceInspector: use a freshly-fetched ftid when the place hasn't stored one
