fix(mariadb): disable binary logs by default

[mrrobot47]

Summary

• Disable MariaDB binary logging by default in the EasyEngine MariaDB image.
• Remove the default log_bin, log_bin_index, binlog_format, expire_logs_days, and max_binlog_size settings from mariadb/ee.cnf.
• Keep the [mysqld] section so the config file remains valid.

Why

EasyEngine does not configure or manage MariaDB replication for the global DB. Enabling binary logs by default causes persisted mariadb-bin.* files to grow without a practical total disk cap.

max_binlog_size only rotates individual files, and expire_logs_days only purges by age during specific server events. High-write installs can still fill disk.

Notes

skip-log-bin is intentionally not added. Removing EasyEngine's default log_bin keeps binlogging off by default without overriding users who deliberately enable binlogs elsewhere.

Pull request overview

Disables MariaDB binary logging by default in the EasyEngine MariaDB image by removing EasyEngine’s explicit binlog configuration from mariadb/ee.cnf, preventing unbounded growth of persisted mariadb-bin.* files on non-replication installs.

Changes:

• Removed log_bin, log_bin_index, binlog_format, expire_logs_days, and max_binlog_size defaults from mariadb/ee.cnf.
• Kept the [mysqld] section so the config file remains syntactically valid.
