feat(profile): auto-update bot avatar, nickname, and away status based on playing song

Add BotProfileManager that updates the bot's TeamSpeak presence when
songs change: album cover as avatar, song info in nickname, away status
toggled on stop/play. Each feature is independently configurable via
REST API and persisted to the database. Permission-safe — features that
fail due to insufficient server permissions are silently disabled until
reconnect. Description falls back to nickname display on TS3 (only
supported via TS6 HTTP Query).
