Merge origin/main: Panoramax, bikeshare Norway/Detroit, cloud filter strength, Overpass cache

Conflicts:
- KartaView viewer moved into the shared photoViewer.js on main; its
  labels now take the provider name ("{name} street-level photo") and
  are translated there.
- Weather: main's cloud filter strength slider, with its labels in t().
- Street Level caption: translated creator line plus main's licence.

Panoramax status and error texts are marked like KartaView's, and
"Panoramax answered HTTP {status}" gets a template in the panel and the
layer row. Catalogs: es/ru 2553 messages each, complete.
