Joomla: Add upload-size support, introduce php-upload.ini, refactor task numbering, update Docker Compose and override logout client_max_body_size

This commit adds dynamic upload size configuration (upload_max_filesize + post_max_size), introduces a dedicated php-upload.ini template, mounts it through Docker Compose, renumbers all task files consistently, updates main.yml flow, and overrides client_max_body_size inside the logout role.

Improves clarity, consistency, and brings Joomla in line with other IN roles.
