refactor: Remove inline schema creation from PostgresProfileStore in favor of centralized migration system

- Remove AutoMigrate call for profileRow from NewPostgresProfileStore
- Update function comment to reference migration system (make db-migrate) instead of inline schema creation
- Add note that esim_profiles table is created by migration system
- Remove error handling for AutoMigrate execution
