fix(street-level): four regressions from the merge review

- The selected sequence is drawn past the per-tile caps again, and its
  highlight takes every loaded part, drawn or not: in a dense tile a
  clicked Mapillary or Panoramax line kept its cones but lost its line.
- photoViewer tries :fullscreen and :popover-open one at a time, each in
  its own try: Safari before 16.4 parses neither, and the fallback threw
  on every flat KartaView or Panoramax photo.
- A lit Street View off Google 3D says it needs the Google 3D map again,
  instead of "every provider is switched off".
- Chips carry their provider colour again (--chip-color, as on main).

Each comes with the test that reproduced it.
