fix(maps): prevent server crash when legacy Google photo URLs are stored as placeIds

Migration 107 only rewrote image_url rows matching /places/%/photos/%; URLs using
the /place-photos/ or /places/<opaque> paths survived the upgrade and were passed
verbatim to the Places API, producing a malformed request whose empty/HTML response
body threw SyntaxError before detailsRes.ok was checked. The resulting rejection was
leaked by placePhotoCache.setInFlight via an unhandled .finally() chain, triggering
Node 22's default unhandledRejection=throw and terminating the process.

- placePhotoCache: add .catch() after .finally() to prevent unhandled rejection crash
- mapsService: reject URL-shaped placeIds early; read response as text before JSON.parse
- migrations: add migration to rewrite remaining googleusercontent/places.googleapis URLs
- MapView/MapViewGL: prefer stable proxy URL form of image_url before google_place_id

Fixes #770
