This was brought up by @JSengupta-WMF.

It would be useful to be able to query for wishes that have no assigned focus area.

Developer notes

• ApiQueryWishes should accept unassigned as a value for the focusarea parameter
• Perhaps a new constant WishStore::FILTER_NO_FOCUS_AREA
• Query for static::focusAreaField() => null

Acceptance criteria

When querying action=communityrequests-wishes with focusarea=unassigned, only wishes with no focus area should be returned.

Derived Requirement

Add support for filtering wishes with no assigned focus area in the API and UI:

• Extend ApiQueryWishes to accept focusarea=unassigned.
• Implement WishStore::FILTER_NO_FOCUS_AREA constant for handling this filter.
• Update query logic so that focusarea=unassigned returns only wishes where focusAreaField() => null.
• Ensure no other wishes (with assigned focus areas) are included in the result.

Test Steps

Test Case 1: Query with Focus Area = Unassigned

1. Open the API Sandbox on beta.
2. Run the query:
   
   ` action=query list=communityrequests-wishes crwfocusareas=unassigned format=json `
3. ✅❓❌⬜ AC1: The result returns only wishes without a focus area assigned.
