feat(android): console UI, wake-on-LAN wait-until-up, host edit + TV/tablet polish

Bring the Android client to parity with Apple's gamepad experience and finish
Wake-on-LAN.

- Console/gamepad home: host carousel, aurora chrome, mTLS game-library coverflow,
  and an input-aware legend that switches between gamepad face buttons and a
  TV-remote select-ring + arrows based on the last-used input.
- Wake-on-LAN: the fire-and-forget send is upgraded to wait-until-up
  (WakeController/WakeOverlay: resend + mDNS poll, 90s timeout, cancel/retry,
  fingerprint-matched so a host that cold-boots onto a new DHCP IP still connects),
  plus host edit (touch dialog + console form) with an auto-filled MAC.
- Android TV: brand banner (android:banner), density-aware console scaling, D-pad/
  remote nav (Up = Settings, Down or the pad Select button = host Options),
  emergency stream-exit chord, and 120Hz console refresh.
- Touch UI: settings split into subpages with a tablet NavigationRail, axis-aware
  tab animation (horizontal on phones, vertical on the tablet rail), animated
  settings navigation, and a licenses screen with a back button + the real
  workspace version (read from Cargo.toml).
- Vector Lock/controller icons (no emoji); bundled Geist font.
