Music could be started and controlled with no way to turn it off for
a server. Adds a music_settings table (mirrors the same one
velox-dashboard-api's dashboard toggle reads/writes), a /music toggle
command gated to Manage Server, and checks in /play, /queue, and
/volume so they refuse to run when a server has music turned off.
- Added a logging service to manage server event logs including message edits, deletions, member joins/leaves, and moderation actions.
- Introduced commands to configure logging settings, including setting the log channel and enabling/disabling logging.
- Updated the README to document the new logging features and commands.
- Enhanced moderation commands to log actions taken on members.
