SpiceDB Database Schema Failures: Missing Core Tables

Detects high-severity failures in SpiceDB when critical PostgreSQL migration tables
(e.g., alembic_version, metadata, relation_tuple_transaction) are missing
or inaccessible. These failures lead to complete authorization service disruption.

This rule helps catch issues such as:

• Missing or skipped database migrations
• Corrupt or incomplete datastore initialization
• Unexpected datastore schema changes
