fix(live): preserve channels after empty projection rebuild (#18)

Browse Source 
Treat successful but empty live projections with existing live input as stale, reject them on the frontend, and keep the previous visible channel state during rebuild failures.

Add DOM coverage for the Settings analysis flow and backend serialization coverage for empty projection state.
