feat(street-level): "show me X on Street View" action, street_level view field and sl= links

show_street_level (voice and typed) flies to a place and opens its nearest
street-level photo from Google Street View, Mapillary, KartaView or
Panoramax; Street View switches to Google 3D first. The view model gains a
street_level field, share links carry sl=<source>,<lat>,<lon>, and
show_in_gods_eye_view can open a photo. A plain sl=google link only arms the
point and waits for OPEN, so it never bills a key without a click.

Embed pages show an open photo in an overlay that Esc closes. On-screen
strings are translated into es, ru, zh-CN and zh-Hant. Covered by unit tests
and three new steps in the Street Level browser suite.

If you choose **USE CHATGPT OAUTH** in Provider Settings, the local server uses that sign-in only to mint the same kind of short-lived Realtime credential, and refuses the OAuth path for non-loopback clients.
