feat(apple): the gamepad UI comes to tvOS - focus-driven, with real session controls

The console UI now runs on tvOS through the NATIVE focus engine: carousel
cards and settings rows are focusable Buttons (Siri Remote and pads both
navigate; imperative scrollTo replaces the drop-prone scrollPosition binding),
while iOS/macOS keep the 60 Hz poll untouched - on tvOS it carries only what
focus has no concept of: X/Y screen actions and left/right value adjust with
the poll's dominant-axis feel (onMoveCommand proved input-source-dependent:
keyboard intercepted, pad dpad not -> double steps). Text entry uses the
system fullscreen keyboard (TVTextEntry); pairing + library present as covers
under the launcher; the game library defaults ON; settings values slide a
quiet 14 pt in the step's direction.

Session controls: controller/remote input routes EXCLUSIVELY through
GameController during a stream (GCEventViewController, interaction disabled) -
a pad's B no longer doubles as a UIKit menu press that ended sessions
mid-game. Deliberate exits only: the cross-client escape chord (hold
L1+R1+Start+Select 1.5 s - pf-client-core's contract, now implemented on all
Apple platforms) and holding the remote's Back >= 1 s; the start-of-stream
banner (now also on tvOS) teaches both. The Siri Remote's touch surface
drives the host pointer - press = left click, Play/Pause = right click,
release-tail jumps gated so motion stays truly relative.

tvOS 26 regressions fixed at the root: the app-wide brand tint rendered every
unfocused control as a blank pill (tint dropped on tvOS) and the 17 pt root
font shrank the whole platform (29 pt there), plus 10-foot sizing across host
cards, the gamepad screens, and the stats HUD (whose misleading "Press Menu"
hint is gone). Acknowledgements scrolls by focus-sized chunks and Menu pops
instead of suspending; full-width focusSections make the home actions
reachable from any column. The presenter defaults to stage-3 glass pacing on
tvOS (a 60 Hz panel fed a 60 fps stream is the sticky-FIFO worst case behind
the 50 ms display stage) and is pickable from the gamepad settings; HDR
capability advertises from AVPlayer.eligibleForHDRPlayback instead of the
current mode's EDR headroom, so an SDR home screen no longer hides an HDR TV.
