feat(apple): wake-until-up overlay + host edit with MAC prefill

- HostWaker + WakeOverlay: after sending the Wake-on-LAN packet, wait until the host
  is really back (resend + mDNS poll, timeout, cancel/retry) before connecting.
  macOS-only in practice — WoL stays gated off on iOS/tvOS pending the multicast
  entitlement.
- Add/Edit host sheet gains a Wake-on-LAN MAC field, prefilled from the stored MAC
  or the live mDNS advert; parseMacs validates aa:bb:cc:dd:ee:ff.
- Gamepad chrome/home and glass-style polish.
