Categorize shared components

[orangesunny]

Describe the problem

Components shared from different projects are not possible to put into categories in the end project.

Solution brainstorm

Enable categorization of the shared components.

The Organize or remove menu will need to be reworked to let users set the categories in the end projects comfortably.

On the model side, this will need to change Component.links to use an intermediate model (through) to store Category (the migration is described at https://docs.djangoproject.com/en/5.2/howto/writing-migrations/#changing-a-manytomanyfield-to-use-a-through-model). The listing of components in categories then needs to be modified similarly that is currently used for a project.

On the UI side, this probably should move out of component settings to the Organize tab, where an option to select category in each linked project would be available. Ask @KarenKonou if you need help with the frontend.
