Post-merge fixes: remove duplicate IncomingCallNotification, restore PiP touch drag + grip dots, show redacted message content

- Router.tsx: remove IncomingCallNotification (CallEmbedProvider.IncomingCallListener now handles all calls)
- CallEmbedProvider: restore touch drag (handlePipTouchStart), grip dots on resize handles, fix normaliseToTopLeft width/height
- FallbackContent/MsgTypeRenderers: add originalBody prop to show struck-through original text on deleted messages
- RoomTimeline: cache text message bodies so they can be shown after redaction
