📈(frontend) capture media diagnostics on media errors

Attach a media diagnostics snapshot to the room event handler for
media exceptions. The snapshot captures the state of the user's
setup at the moment of the error (available devices, permission
state, active tracks, etc.), so support has enough context to
troubleshoot user issues without asking them to reproduce.
