refactor(backup): inline backupbot hooks, drop mysql_backup.sh

Move the mysqldump/gunzip commands directly into the
backupbot.backup.pre-hook / backupbot.restore.post-hook label values
on the db service and delete the external mysql_backup.sh + its
config mount + MYSQL_BACKUP_VERSION. Matches the inline pattern used
by akaunting / engelsystem / forgejo and removes one file from the
recipe surface area.
