Notes from the Product Manager:
Users have been adding bad data to our records. Let's fix that.

User Story:
As a GreenGuardian CRM Director, I want the system to enforce validations that prevent users from saving a Garden record with negative values in specific fields, to ensure the logical consistency and accuracy of the data

Acceptance Criteria:

• Maximum Plant Count, Minimum Plant Count, Total Plant Count, and Total Unhealthy Plant Count must always be non-negative. Attempting to enter a negative value should prompt an error message: "Plant Count fields must be greater than or equal to zero."
