Title

Add icon Column to Category Table

Description

This pull request introduces a new icon column to the category table in our database. The purpose of this addition is to enhance the visual representation of categories in our application by associating each category with a unique icon. All areas of the codebase that create or update category records have been updated to include this new field.

Changes

• Added a new icon column to the category table in the database schema.
• Updated all INSERT and UPDATE queries for the category table to include the icon field.
• Updated the controller logic to process the icon field during category creation and updates.
• Adjusted the API responses to include the icon field where category data is returned.

Testing

• Manual testing was performed to ensure that categories can be successfully created and updated with icons through the UI.
• Automated tests have been updated to cover the new icon field in category creation and update scenarios.

Additional Notes

• The icons are expected to be stored as URLs pointing to the icon svg.
