Show Windows privacy hints in launcher

The launcher sentence around the room name was replaced
by a standalone instruction ("meetingText"); the room name
now sits on its own line below it.

Windows users additionally get camera/microphone
permission instructions in the launcher view. The block
reuses the existing i18n/OS detection and only appears
when translations loaded, so a failed i18n.json fetch
cannot render an empty box.
