🔧 FIX: Prevent 'role root does not exist' PostgreSQL error

start.sh:
- Added fallback defaults for DB_USER, DB_HOST, DB_DATABASE, DB_PASSWORD
- Ensures psql always uses 'postgres' user even if env vars missing
- Added debug logging to show which credentials are being used

complete_schema.sql:
- Permissions Protocol now checks if directus_policies table exists first
- Silently skips on first boot (before Directus creates its tables)
- Prevents SQL errors during fresh install
