feat(clients): Wake-on-LAN in apple/linux/windows/android/decky

Each client learns a host's MAC from the mDNS `mac` TXT while it's awake, persists it on the saved-host record, and — when reconnecting to an offline host — sends a magic packet before connecting, plus an explicit "Wake host" action. Apple wraps the C-ABI; linux/windows call the core fn directly (linux also gains a --wake CLI mode); android via a new nativeWakeOnLan JNI export (the mDNS browse record gains a 7th mac field); decky shells out to the linux client's --wake before launching the stream. iOS/tvOS need the managed com.apple.developer.networking.multicast entitlement (pending Apple approval), so the wake path + UI are gated off via PunktfunkConnection.wakeOnLANAvailable and the entitlement is commented out — keeping iOS/tvOS releasable. MAC-learning stays active on every platform so it lights up the moment it's ungated. macOS works today. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

+	<!-- Wake-on-LAN needs to send a UDP broadcast magic packet (a sleeping host has no ARP
+	     entry, so unicast can't wake it). Since iOS 14 / tvOS 14 the OS blocks sending to
+	     broadcast/multicast addresses unless the app carries this managed entitlement — it must
+	     be requested from and approved by Apple for the App ID, then enabled in the provisioning
+	     profile. macOS is not gated by this (its App Sandbox network.client/server cover it).
+
+	     GATED pending Apple's approval of the request (form filed) — an unauthorized managed
+	     entitlement breaks iOS/tvOS signing, so it's commented out to keep those apps releasable.
+	     ON APPROVAL: (1) uncomment the two lines below, and (2) flip
+	     PunktfunkConnection.wakeOnLANAvailable (PunktfunkConnection.swift) to enable the iOS/tvOS
+	     wake path + UI. Until then iOS/tvOS Wake-on-LAN is a clean no-op — MACs are still learned
+	     from mDNS so it works immediately once ungated. macOS is unaffected (separate entitlements
+	     file, no multicast entitlement needed). -->
