Play without the theatre surround if SteamVR refuses it

Review (SWE-2 Max): a non-standby error creating the cosmetic surround
at startup still ended playback before the screen appeared. Theatre now
logs it and plays without the surround. close() treats any per-overlay
teardown error as best effort (signals are already ignored there).
