Reorganise Infrastructure/Services into feature namespaces

- Move registration marker interfaces to Registration/Abstractions - Add feature folders with Abstractions subfolders: EffectiveConfig, Dnsmasq/Config, Dnsmasq/Hosts, Dnsmasq/Leases, Dnsmasq/Reload, Logs, Updates, UI/Settings, Common/Process - Place interfaces in each feature's Abstractions namespace; align implementation namespaces to folder paths - Update Program, extensions, controllers, hubs, helpers, components, and tests to use new namespaces - Remove old flat Services/Abstractions and root-level service files
