Status filtering includes items that are mapped to different statuses
### Problem
When filtering work items by status, the filter incorrectly includes items that would actually display a different status due to active status mappings.
### Example Scenario
1. Item has `system_defined_status_id = 1` (system "to do" status)
2. Custom status "To Do" exists with `converted_from_system_defined_status_identifier = 1`
3. Status mapping exists: "To Do" → "In Progress" for task work item type
4. Item is a task, so it displays as "In Progress" in the UI
5. **Bug**: Item appears in filter results when filtering by "To Do" status
### Expected Behavior
Items should only appear in filter results if their **resolved status** (after applying mappings) matches the filter criteria.
### Current Behavior
Items appear in filter results if their **raw status data** matches the filter criteria, ignoring status mappings.
### Impact
- Users see incorrect items in filtered lists
- Status-based workflows become unreliable
- Confusion between what users see in the UI vs. filter results
### Acceptance Criteria
- [ ] Items mapped away from the filtered status are excluded from results
- [ ] Items that map TO the filtered status are included in results (existing behavior)
- [ ] Time-constrained mappings are respected
- [ ] Both custom and system-defined statuses work correctly
- [ ] Different work item types are handled appropriately (mappings are type-specific)
