Document control panel paths in MySQL restore script header

Added comprehensive documentation to script header:
- Lists all 4 control panel paths (cPanel, Plesk, InterWorx, standalone)
- References source: lib/system-detect.sh -> SYS_USER_HOME_BASE
- Documents InterWorx special case (/chroot/home vs /home symlink)
- Shows restore directory and SQL output directory formats
- Makes it clear where paths come from for maintenance
