refactor(apple): decompose ContentView (735 -> 272 lines)
Split the monolithic ContentView into focused view files — a pure structural refactor
with no behavior change (verified: builds macOS/iOS/tvOS, the test suite is green, and a
fidelity review against the original found no discrepancies):

- ContentView (272): the coordinator — owns the session model / host store / discovery,
  switches home<->session, holds the connect logic (it reads @AppStorage) + the dev
  hooks, and the stream builder (whose stable identity across awaiting-trust->streaming
  must NOT move — it stays here).
- HomeView (251): the hosts grid + navigation + toolbar + sheets + "On this network"
  discovery section + empty state.
- HostCards (158): HostCardView + DiscoveredCardView, sharing a CardMetrics struct
  (dedupes the platform-tuned sizing the two cards had copy-pasted).
- TrustCardView (80): the TOFU prompt + fingerprint formatting.
- StreamHUDView (67): the streaming overlay HUD.

State flows idiomatically: @StateObject (ContentView) -> @ObservedObject in subviews,
@State -> @Binding; the connect logic is passed as closures. Sheet placement is
preserved — the pairing/speed-test sheets stay on the outer body so they survive the
trust->home transition.
