fix(voice): screen share restore is best-effort — Discord session teardown race

GoLive (dank074 Streamer) needs the single voice session; after the stream
ends, an automatic @discordjs/voice reconnect often races Discord's session
teardown and times out (AbortError). Restore is now best-effort with a 5s
delay; if it fails the FE shows disconnected and the user clicks Connect —
an accepted tradeoff for one-voice-session-per-user.
