Reorganize migrations for new vs existing deployments

- Created core/ directory for essential migrations that always run - Created legacy/ directory for migrations only needed when upgrading - New deployments will only run core migrations for a clean database - Existing deployments will run all migrations in proper sequence - Fixed duplicate migration numbers (014 and 027) - Updated migration runners to handle new directory structure - Added README explaining the migration organization This change optimizes deployment for new users who will get a clean schema without running unnecessary upgrade migrations.
