Replace the error-string-matching migration runner with a proper schema_version table. Migrations are now numbered and recorded; only unapplied versions run. Fresh databases seed at baseline version (CREATE TABLE already includes all columns). CREATE TABLE statements updated to include regions (sites) and node_id (check_history) — previously only added via ALTER. DeleteAlert now nulls sites.alert_id before deleting, preventing dangling references that caused every incident to hit the error path instead of alerting.
