Run validate_schemas.sh before pushing any SQL schema change

Run projects/ores.sql/utility/validate_schemas.sh locally before pushing any change that adds, removes, or renames SQL schema files (create or drop scripts). A clean run ends with = Validation Passed = and zero warnings.

Why: A PR was pushed without running it and CI went red on a missing drop script the validator catches in ~1 second locally.

How to apply: After any change under projects/ores.sql/create/ or projects/ores.sql/drop/, run the validator before git push.
