fix(street-level): the panel respects restores, modes, focus and keys

From gekh's review of #768, each with a test that fails before:

- P2: the panel no longer reopens on every page load. The shell reports
  who asked for Street Level to switch on; only a user, voice or tool
  request (isExplicitLayerStateOrigin) or an opening photo opens it, and
  those automatic opens are never stored. Without the hook, a stored or
  shared "collapsed" choice wins during the restore window.
- P2: the expanded photo hides in Clean View, recording and the cockpit,
  and holds neither Esc nor Tab while hidden.
- Esc/Tab are taken only from the viewer, body or globe, not app-wide;
  FIT/FILL show the right choice while expanded; a 0x0 viewer is never
  resized (no z=NaN tile request); the expanded viewer keeps the panel's
  CSS tokens; KEY REQUIRED hides the raw "no_key" code.
- Share links carry the panel's collapsed state (ui token t); the Cyber
  theme frames the panel like its rail peers (the pinned Cyber selector
  tests now list it).
- Accessibility: radiogroups move with arrow keys and are one tab stop,
  their focus ring is no longer clipped, and the provider chips sit
  outside the disabled fieldset so the "how to add the key" hint stays
  reachable (a gated chip explains instead of toggling).
- Renders write only changed attributes (the rail's MutationObserver
  relaid out on every write); one coalesced resize per open; the legacy
  render-mode key migration is gone.
