Partially edit catalogue categories

[VKTB]

Description

This PR creates a catalogue items endpoint (accessible at /v1/catalogue-categories/{catalogue_category_id}) to which PATCH requests can be sent to partially update a catalogue category by ID. The endpoint requires only the fields that have changed to be supplied. For example, if the name needs to be changed then only the name field and corresponding value should be supplied.

Supplying a list of catalogue item properties in a PATCH request for a catalogue category that is not a leaf returns 500 error. The catalogue category gets updated in the database which should not happen because a non-leaf category cannot have catalogue item properties.

Can you add error checking for the Manufacturer URL to test if it's a valid URL? I've had to add this in the frontend because if the URL is invalid and a user clicks on it, it appends the invalid URL to the current URL. This would also needs to be done in #67.
