Fix Confluence & BookWyrm setup:

- Add docker compose build trigger in docker-compose tasks
- Cleanup svc-prx-openresty vars
- Enable unsafe-inline CSP flags for BookWyrm, Confluence, Jira to allow Atlassian inline scripts
- Generalize CONFLUENCE_HOME usage in vars, env and docker-compose
- Ensure confluence-init.properties written with correct home
- Add JVM_SUPPORT_RECOMMENDED_ARGS to pass atlassian.home
- Update README to reference {{ CONFLUENCE_HOME }}
