fix(map): Unify label/polygon click paths and fix boundary fitBounds

Fix A: Label click now also queries polygon layers
- When clicking park/forest/cemetery labels, also query landuse_park
  fill layer to get polygon geometry
- If polygon found, use it as boundary directly from rendered tiles
- Eliminates need for API round-trip for park boundaries

Fix B: Boundary fitBounds behavior changed
- If boundary EXISTS: ALWAYS fitBounds (zoom in OR out) to show
  the full boundary - the boundary defines what user should see
- If NO boundary: NEVER change zoom for map clicks/label clicks
- Search results: fly to center but preserve current zoom level

Removed previous z14 cap and zoom-in-only logic - boundaries now
always control the camera as expected.
