feat(ui): green map pin for applied flats, hide map reject after apply, lightbox image viewer

Map: replace Leaflet's default marker with a divIcon SVG pin coloured
per state — green when the user has already successfully applied
(status.chip === "ok"), brand-blue otherwise. Same condition also hides
the action buttons in the popup, matching the list view, which already
hid both Bewerben and Ablehnen on success — so the only remaining
action on an applied flat is opening the original ad link.

Image gallery: clicks now open a global lightbox modal instead of a new
tab. The viewer fits each image into the viewport via max-width/height
+ object-fit: contain (uniform sizing regardless of source aspect),
shows × top-right, prev/next arrows on the sides, ←/→/Esc keyboard
nav, and click-on-backdrop to close. Prev arrow is hidden on the first
image and next on the last. Tile changes from <a target="_blank"> to
<button> since the new-tab fallback is no longer wanted.
