The tile URL was built as `${env.API_BASE_URL}/tiles/{z}/{x}/{y}.png`,
which has three problems on a real deployment:
1. Wrong path segment: the backend serves tiles under /map/api/tile/
(singular), not /tiles/.
2. Wrong extension: the backend emits .jpeg, not .png.
3. Wrong base: API_BASE_URL may be empty or point at the JSON API host.
Tiles are served by a dedicated upstream behind the same reverse
proxy that fronts the React SSR, so they must be same-origin and
relative (matches Angular environment.mapApiUrl).
With this fix, the map renders its base tiles on the deployed site
instead of issuing doomed requests and showing a blank canvas behind
the markers. The Leaflet marker layer was already rendering; only the
tile layer was missing.
