## Database Disk Usage Monitor

**New Features:**

* Added a **disk usage monitor daemon** that periodically checks storage consumption.

* Sends **warning emails** to administrators when usage crosses a configured threshold.

* **Blocks insert/update operations** when usage exceeds a higher critical threshold.

* Introduced **configurable environment variables** for warning and blocking thresholds with validation.

* Integrated disk usage checks into both the **FastAPI app** and **gRPC serve** to enforce write blocked.

**Enhancements:**

* Extended the email sender with a method and HTML template specifically for **disk usage alert notifications**.
