[FIX]: [PHOENIX] [BE] Set Maximum Character Limit Validation for Description Field in Add Product Modal

[Olnuel]

Description

Implement API validation for a maximum character limit for the "Description" field in the "Add Product" modal. This validation should ensure that any product description entered by the user does not exceed the specified character limit. If the limit is exceeded, an appropriate error message should be returned to the frontend.

Acceptance Criteria

1. Ensure a maximum character limit of 170 characters for the "Description" field when adding or editing a product.
2. If a user attempts to submit a description that exceeds the character limit, the backend should reject the request and return a validation error message.
3. The error message returned should indicate that the description exceeds the maximum allowed length and specify the character limit.

Endpoint

POST /api/products
