Map loading: replace fuzzy ghost-pin blobs with a clean top bar + pill

The cold-start loading state scattered fuzzy pink "ghost pins" across the map
(the same blob look that was disliked on real markers) which read as broken.
Removed MapSkeletonPins entirely.

New loading state, per the agreed plan (keep the map instant, never cover it):
- A slim animated top progress bar ("ss-loadbar" sweep on a faint track) that
  sits above the map while spots stream in.
- During a genuine cold start (no markers yet), a small labeled "Loading spots"
  pill with a spinner near the top — honest about what's happening (querying
  relays), not fake pins on the ocean.
- Reduced-motion respected (bar becomes static).

The map itself is untouched and still renders immediately; only the placeholder
changed. Dropped the now-unused MapSkeletonPins import. Build clean, no console
errors.
