feat: poll voting, location sharing, image captions, message forwarding

- Poll voting: PollContent sends m.poll.response on answer click
- Location: MLocation shows OSM map embed + share-location button in toolbar
- Image captions: caption field on media uploads sets message body
- Message forwarding: ForwardMessageDialog with searchable room picker
- Also includes ring timeout fix and earlier session patches
