feat(FN-2640): align planning labels across agent log and tests

- Rename Planning/Triage label to Planning in Agent Log model metadata and related assertions
- Map triage agent badge display name to Plan while preserving existing labels for other agent roles
- Update TaskDetailModal and AgentLogViewer tests to match the revised planning terminology
- Stabilize dashboard TUI QR payload test by waiting for label and payload text separately with explicit timeouts
