Add migration test

[michalkrzyz]

If we want to have this kind of test in testrun we would need to consider:

• detect schema change and run tests conditionally
• use randomized mariadb schema

Pull request overview

Adds a CI mechanism to run a “migration up/down” smoke test only when MariaDB migration files change, to keep PR test runs fast while still validating schema migrations when relevant.

Changes:

• Add Makefile targets to detect migration changes and run an up/down migration test against a dedicated schema.
• Update CI workflow to fetch base ref, detect migration changes, and conditionally run the migration test.
• Refactor create-migration to use the shared MIGRATIONS_DIR variable.
