Joshua King 5db49b3d29 fix: whole-file read-only integrity preflight on the executor, rollback-journal fixture ...

- preflight now runs PRAGMA integrity_check (whole-file validation,
  not just sqlite_master) over a mode=ro connection, dispatched via
  hass.async_add_executor_job so the event loop never blocks
- migration-stage corruption test fixture is now a ROLLBACK-JOURNAL
  file created with plain sqlite3 (default journal mode), so the WAL
  transition the guardrail protects against actually happens in the
  test instead of being masked by an already-WAL fixture
