feat(apple): default-UI connect/wake modal, auto-wake toggle, pixel-exact windowed streaming

Three client-UX changes that share the connect/present path (and settings files):

- Connect/wake overlay is now mode-aware: the console/gamepad UI keeps the
  full-screen aurora takeover, while the default (touch/desktop) UI shows a
  Liquid Glass modal over the host grid — the takeover looked out of place there.
- Add an auto-wake toggle (DefaultsKey.autoWake, default on) across macOS/iOS/tvOS
  Settings + the gamepad settings view; gate startSession/prepareWake and the
  gamepad "Wake & Connect" label on it. MAC-address learning stays always-on.
- Windowed sessions now stream at the window's native pixels (Match-window
  default-on) so the picture is 1:1 pixel-exact instead of the presenter
  resampling a fixed-mode frame; fullscreen reports full-display px, also 1:1.
  Also lands the mid-resize aspect-fit tracking (decoded contentSize) that keeps
  the picture undistorted after a resize.

swift build + swift test (121 tests) green; screenshot scenes verified.
