Commands for everything a dashboard can do

- /music skip, pause, resume, stop, repeat, remove, move (DJ role)
- /config view, clear, toggletwitch, streamers, beta-features (server owner)
- /slvl status, remove-reward; /moderation bans, timeouts; /security history
- /beta is now the bot owner's DM-only command: set, off, servers, remove-server, status
- betasettings service and repo methods, with integration tests
