Related to #952 and #971
Both issues were caused by the backend not sending required fields to the
frontend in the ToFrontend() converters:
Issue #971 (Agent required badge):
- NodeFrontend was missing LinkedHostAgentId field
- Frontend couldn't identify linked host agents, so it fell back to showing
'Agent required' instead of 'Via agent'
Issue #952 (AI Commands toggle stuck):
- HostFrontend was missing CommandsEnabled field
- Frontend couldn't see the actual commandsEnabled state from the backend,
causing the optimistic UI to never receive confirmation that the state
had actually changed
Also added IsLegacy and LinkedNodeId to HostFrontend for completeness.
