+startup applies the checked-in dashboard migrations before reads or writes. If
+the app is launched from outside the repo tree, set `DASHBOARD_MIGRATIONS_DIR`

 Stored dashboard documents pass through a version migration boundary before
 reads or writes; the MVP supports `dashboard.v1` and fails unsupported versions
 with an explicit migration error.
