fix(quic/apple): QUIC keep-alive + reconnect input re-engage
Three native-client bugs isolated against a stock Moonlight client (which
stays connected / keeps input working under the same actions):

- Connection drops mid-stream: the quinn endpoints (host + client) ran with
  default transport config, so keep_alive_interval was OFF. Any quiet stretch
  (no input, audio muted/stalled, a capture hiccup, a mode change) let the
  idle timer expire and quinn closed the session -> next_au=Closed -> "Session
  ended". Moonlight's ENet sends keepalive pings; we sent nothing. Add a shared
  TransportConfig (keep-alive 4s under an explicit 20s idle timeout) to both
  endpoint::server_from_der and endpoint::client_pinned_with_identity.

- Reconnect input dead (macOS): the session-start auto-capture one-shot was
  consumed even when engageCapture(fromClick:false) was refused (window not key
  yet at the instant of reconnect), with no retry -> capture stayed off and
  input never forwarded. Clear the one-shot only on a successful engage, and
  retry on NSWindow.didBecomeKey. Stays scoped to session start, so it does not
  resurrect the rejected auto-grab-on-activation behavior.

- Reconnect input dead (iOS): wasCapturedOnResign leaked stale state across
  sessions and the foreground-restore could fire before this session's
  InputCapture was wired (setForwarding no-ops on nil). Reset it per session in
  start() and guard the didBecomeActive restore on inputCapture != nil.

Validated: cargo build -p punktfunk-core --features quic; swift build;
swift test (39 passed, 0 failures); xcframework rebuilt (all 5 slices), no
ABI/header drift.
