Replaced duplicated inline build definitions in multiple docker-compose.yml.j2
templates with a shared include (roles/docker-container/templates/build.yml.j2).
This ensures consistent use of pull_policy: never and Dockerfile context across
services (Postgres, Bookwyrm, Bridgy Fed, Chess, Confluence, Jira, Moodle,
OpenProject, Pretix, Roulette Wheel, WordPress, XWiki, Simpleicons).

Confluence: README added; demo disables OIDC/LDAP; Dockerfile overlay; docker-compose now uses CONFLUENCE_CUSTOM_IMAGE and DB depends include; env.j2 adds ATL_* and JVM_*; vars use integer math (//) for Xmx/Xms and expose CUSTOM_IMAGE.
Jira: initial role skeleton with README, config/meta/tasks; Dockerfile overlay; docker-compose using JIRA_CUSTOM_IMAGE and DB depends include; env.j2 with proxy + JVM envs; vars with integer-safe memory sizing.
