refactor: reorganize docker role into logical service groups

Break down the monolithic main.yml (176 lines) into organized service categories:

- infrastructure/ (caddy, authentik, dockge) - Core platform components
- development/ (gitea, codeserver, conduit) - Development tools
- media/ (audiobookshelf, calibre, ghost, pinchflat, etc.) - Content services
- productivity/ (paperless, baikal, syncthing, mmdl, etc.) - Personal organization
- monitoring/ (glance, changedetection, appriseapi) - System monitoring
- communication/ (gotosocial, postiz) - Social/messaging services

Benefits:
- Improved maintainability with logical grouping
- Better dependency management between service categories
- Enhanced tag-based deployment (can deploy by category)
- Cleaner organization for 25+ services

All individual service tags remain functional for backwards compatibility.
