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.
