fix(nosignal): hardware-test feedback — additions icons, power menu, weather picker

From the 2026-06-15 hardware-test feedback (redesign passed end-to-end):

- Glyphs: map the 12 unmapped additions-page icon names (brush, cloud_sync,
  data_object, deployed_code, movie_edit, neurology, psychology, robot_2,
  smart_toy, sports_esports, videocam, vpn_lock) so the nexus Additional
  Software page stops rendering "?" boxes. Verified Nerd Font codepoints.
- Glyphs: cp() now uses String.fromCodePoint, not fromCharCode — the 5 MDI
  glyphs above 0xFFFF were being truncated by the 16-bit fromCharCode.
- Shortcuts: Super+Escape (session) now drives the redesigned full-screen
  Power Menu via NsShell.toggle("power"); old caelestia session panel is
  now dead code.
- nexus LanguageAndRegion: replace the "coming soon" weather placeholder with
  a real location input bound to GlobalConfig.services.weatherLocation (the
  Weather backend already geocodes / IP-auto-detects).
