I have read the CONTRIBUTING.md file.

YES

What kind of change does this PR introduce?

Test utilities

What is the current behavior?

E2E tests that need to verify database state go through the SQL Editor, which is unnecessarily slow and prone to future breakage.

What is the new behavior?

Adds shared db utils for checking database state in Studio E2E tests by querying the database directly. Refactors API access tests to use the new utilities.

Additional context

Summary by CodeRabbit

• Tests
  • Refactored API access privilege verification to use direct database queries instead of SQL editor interaction.
  • Added database utility functions for e2e tests to query table existence and access privileges.
  • Updated test signatures to simplify privilege verification calls.
