fix: Update migration to properly set SignRequest status

- Add postSchemaChange method to migrate existing data
- Set status = 2 (SIGNED) when signed IS NOT NULL
- Set status = 1 (ABLE_TO_SIGN) when signed IS NULL and file.status = 1
- Status 0 (DRAFT) remains as default
- Only update records with status = 0 to avoid overwriting
