fix(rmeets): add recording button + post-meeting transcript link

- Add "recording" to Jitsi toolbarButtons in both clean room mode
  and folk-jitsi-room shell mode so users can trigger Jibri recording
- Add "View Transcript & Summary" link on meeting-ended screen
- Jibri network connectivity fixed on Netcup (was on wrong Docker
  network, couldn't reach Prosody XMPP)
