Confluence/Jira roles: add READMEs, switch to custom images, proxy/JVM envs, and integer-safe heap sizing

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.
