feat: show conflict and error badges in header

meshd | mini | ⚠ 2 | ✗ 1 — yellow conflict count and red error count
appear next to device name, separated by pipes, only when nonzero.
Conflict count updates from ConflictsLoadedMsg; error count from
FolderStatus.Errors (already polled by the dashboard event loop).
