Maurice 5aa36aaf3d fix(maps): stop the index costing a second search, a duplicate and a lost cache ...

Six things the merged search and the offline cache got wrong.

An index failure took the OpenStreetMap answer down with it. Only the OSM half
of the Promise.all had a catch, so a rejection on the index side discarded ten
results that had already arrived and sent the same query to Nominatim a second
time, behind its 1.1 s process-wide throttle. The index refusing a query is
ordinary traffic rather than an outage — a common single word without
coordinates is turned down upstream as too expensive — so this fired in normal
use. Each side now catches its own failure, and the keyless fallback reuses the
answer OpenStreetMap already gave instead of asking again for a list that
cannot have changed.

Dedup never fired for a non-Latin name. namesOverlap splits on [^a-z0-9], so
長谷寺, Кремль and مسجد الشيخ زايد all tokenise to nothing and the function
returned false — the same place came back once from each source, one row under
the other, and picking either gave it a different id. That is the corpus this
whole feature was measured on. Two names with no Latin words are now compared
strictly, folded through NFKC so the width variants the sources disagree on
still match; sharing a character is deliberately not enough, because deduping
東京タワー against 東京タワー駅前郵便局 would swallow a real result.

expand=1 answered nothing for an index place while expand=0 answered in full.
The expanded lookup degrades OSM ids to the plain one and had no branch for the
new family, so the richer request was the poorer one, over REST and MCP alike.

The bias circle could exceed Google's 50 km ceiling. A trip spread over more
than that produced a radius Google rejects outright, turning a search into an
error toast. Clamped on both sides — the client because it draws the box, the
server because the radius arrives over the wire.

The offline cache was rebuilt on every sync and never deleted. syncTrip wrote
its meta row with put(), which replaced the whole record and dropped the
fingerprint saying the cached area was current, so every login, reconnect and
manual sync re-downloaded megabytes that had not changed. And clearTripData
never touched areaPlaces, so a trip switched off for offline use kept answering
offline searches and its rows stayed for the life of the install.
clearCachedPlaces, which claimed to do that job, was called from nowhere; its
only test asserted with .every() on an empty table and passed on nothing.

Picking an offline suggestion ended in an error toast. The details lookup had
no cache path, so it failed and the callers fell back to searching for
"name, address" — which the cache matches on the folded name alone, so it found
nothing for a place that was sitting right there. A miss stays a miss.
