Oliver Jakoubek 4e856cd206 feat: add category write operations (create, update, remove, get-by-name)
Add CreateCategory, UpdateCategory, RemoveCategory, and GetCategoryByName
methods to the client, with BoardScope wrappers for project-scoped operations.
Includes comprehensive tests for all new methods.

Closes kanboard-4n3
