feat: Agent reports CommandsEnabled status to server. Related to #903

- Add CommandsEnabled field to AgentInfo in pkg/agents/host/report.go
- Agent now reports whether AI command execution is enabled
- Server stores and exposes this via Host model
- Frontend can now show which agents have commands enabled
- This provides visibility before implementing remote configuration
