Summary

Update SQLAlchemy model definitions to use Mapped[T | None] with explicit nullable=True for columns where the database allows NULL values but the ORM previously implied NOT NULL.

Affected columns:

  • app_triggers.provider_name
  • operation_logs.content
  • providers.quota_used

This resolves flask db check validation failures in CI/CD workflows.

Close #30473
