Add configuration for secured connection between database server and client

[Copilot]

Pull request overview

This PR adds optional TLS/SSL configuration for MariaDB/MySQL connections in the Docker iTop environment, wiring certificate mounts into the DB/client containers and documenting how to enable secure transport.

Changes:

• Mount DB/webserver certificate directories into services (PHP, DBs, Adminer) and add a PHP client config (client.cnf).
• Extend documentation to describe TLS enablement and Adminer SSL usage.
