feat: encrypted-history prompt, incoming-call alerts, message edit, panic button (v1.7.0+11)

P1 key_restore_prompt: offer recovery-key restore right after login
P2 incoming calls: mount overlay in app.dart + detect MSC3401 call.member
   (Element X signalling) — calls were previously invisible
P3 message edit: editMessage/EditMessage + Edit dialog (reactions/delete
   were already wired)
P5 panic button: new feature/panic module — hold-to-send alert text +
   m.location to a configured room; alert sent before geolocation so a
   denied permission never blocks it

All verified end-to-end in headless Chromium against production build.

// Version: 1.0.0 | Created: 2026-07-04
// Panic button repository — config in Matrix account data plus the trigger
// action: send an alert text message and (when the browser grants it) an
// m.location pin to the configured room.
//
// The alert message is sent FIRST so a denied/slow geolocation permission can
// never block the emergency alert itself.
//
// NOTE web-only geolocation (dart:js_interop + package:web). When native
// Android/iOS builds happen, gate this behind a conditional import.
