Refactor Akaunting role and CSP handling

- Improved CSP filter to properly include web-svc-cdn and use protocol-aware domains
- Added Todo.md with redis and OIDC notes
- Enhanced Akaunting role config with CSP flags and redis option
- Updated schema to include app_key validation
- Reworked tasks to handle first-run marker logic cleanly
- Fixed docker-compose template (marker, healthcheck, setup flag)
- Expanded env.j2 with cache, email, proxy, and redis options
- Added javascript.js.j2 template for SSO warning
- Introduced structured vars for Akaunting role
- Removed deprecated update-repository-with-files.yml task
