Split config_file_service.py into three specialized service modules

Browse Source 
Extract jail, filter, and action configuration management into separate
domain-focused service modules:

- jail_config_service.py: Jail activation, deactivation, validation, rollback
- filter_config_service.py: Filter discovery, CRUD, assignment to jails
- action_config_service.py: Action discovery, CRUD, assignment to jails

Benefits:
- Reduces monolithic 3100-line module into three focused modules
- Improves readability and maintainability per domain
- Clearer separation of concerns following single responsibility principle
- Easier to test domain-specific functionality in isolation
- Reduces coupling - each service only depends on its needed utilities

Changes:
- Create three new service modules under backend/app/services/
- Update backend/app/routers/config.py to import from new modules
- Update exception and function imports to source from appropriate service
- Update Architecture.md to reflect new service organization
- All existing tests continue to pass with new module structure

Relates to Task 4 of refactoring backlog in Docs/Tasks.md
