Ticket `00001KVDETSN6` is complete.

Completed implementation:
- Added a user-visible `dashboard_content_ready` metric that carries and validates a rendered dashboard snapshot rather than treating first frame or a single row as ready.
- Added expected dashboard content coverage for Ticket rows, Pod rows, Companion status, Orchestrator status, orchestration overlay state, action labels, disabled reasons, local Ticket state, and overlay Ticket state.
- Added a real git/orchestration overlay fixture for the local-ready / overlay-inprogress case and validated the visible `ready→prog` / `Wait` row.
- Added negative coverage for missing expected row, wrong state, missing overlay state, and missing action label.
- Added bounded startup source breakdown including pod metadata/status probing, ticket config probe/parse, overlay validation/read/git checks, ticket scan/parse, local claim scan, pod row materialization, and total workspace panel build.
