Subject: [PATCH] fix: replace deprecated mysql backup image with modern cron
 backup container

- The 'databack/mysql-backup' image crashes immediately when used in a pure cron context without legacy arguments and is incompatible with MySQL 8 caching_sha2_password.

- Switched to the actively maintained 'fradelg/mysql-cron-backup' image.

- Re-mapped environment variables to match the new image expectations (MYSQL_HOST, CRON_TIME, MAX_BACKUPS).

- Updated volume mapping destination to '/backup' as expected by the new image.
