Subject: [PATCH] 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
