Complements the existing forward geocoder with Nominatim's /reverse
endpoint so the admin edit form can populate the address from
coordinates (useful when a crawl gave us lat/lng but no street,
e.g. after running crawl-enrich).
Backend:
- geocode.Reverse(ctx, lat, lng) hits Nominatim /reverse with
addressdetails=1 and accept-language=de, reuses the 1 rps mutex
already guarding forward calls. Falls through city → town →
village → municipality → hamlet for small places. Returns nil
when Nominatim has no match so callers can distinguish "no hit"
from "all-empty address."
- New DTOs ReverseGeocodeRequest/Response.
- GeocodeHandler.ReverseGeocode wired at POST /reverse-geocode
behind the same geocodeLimit middleware as /geocode.
Frontend:
- /api/reverse-geocode SvelteKit proxy mirrors /api/geocode.
- MarketForm gets a second button next to "Koordinaten aus Adresse
ermitteln" — "Adresse aus Koordinaten ermitteln". Writes non-empty
street/city/zip back into the form; empty result surfaces
"Keine Adresse gefunden."
