chore: remove unused SQL script and journal entry for sleepy aqueduct migration

- Deleted the SQL script `0122_sleepy_aqueduct.sql` which added a `customEntrypoint` column to the `domain` table.
- Removed the corresponding journal entry from `_journal.json` to clean up migration history.
- Deleted the snapshot file `0122_snapshot.json` as it is no longer needed.
