tripit: enable Nominatim POI geocoding for reel→Wishlist ingest

Forwarded reels (tripit ADR-0031) geocode their venue to map a Saved Place to a
country + city, but the reel route was wired to the global geocoder, which here is
GEOCODER_PROVIDER=openmeteo (city-level, name-based). OpenMeteo returns nothing for
a venue query like "Time Out Market, Lisbon" so reels never resolved and no Saved
Place was created. The app fix (tripit 3c62d596) gave the reel route its own
geocoder behind REEL_GEOCODER_PROVIDER; set it to nominatim on the ingest-plans
CronJob (the only one running the reel route) so forwarded reels resolve to real
venue coords + city + country. Isolated from the global geocoder, which stays
openmeteo for weather/tours. Verified Nominatim resolves the venue from the cluster.
