delete departments(ultimate only)

# Description/Steps to reproduce

i'm pretty ok if at first time it will be a simple link
when you click on it - we just unattach all ingredients, related to this department from grocery list.
this is only for department, that was imported from ultimate template.
I also think that some sort of "unnatach ingredients" thing was covered before, so you need to find this out
maybe we'll setup something simple like a table with information, where we'll have an edit/delete link

then think about removing departments, that was created by user.

# Expected result

# Additional information

No files, tests, or entry points are named. Start by locating the department and ingredient relationship and the handling of departments imported from the Ultimate template; clarify the unlinking behavior and the separate rules for user-created departments before implementation. Done should include agreed behavior for both cases and verification that grocery-list ingredients are handled correctly.
