Fix failing test: CompactFiltersComponent clear button callback

[lc0rp]

Description

The test for CompactFiltersComponent's clear button functionality is failing. The test expects a callback to be invoked when the clear button is clicked, but the callback is not being called.

Failing Test

FAIL  tests/compact-filters.test.ts > CompactFiltersComponent > Assignee Filter Display > should clear all assignees when clear button is clicked
AssertionError: expected "spy" to be called with arguments: [ { people: [], companies: [] } ]

Number of calls: 0

Location

• Test file: tests/compact-filters.test.ts:217
• Test name: "should clear all assignees when clear button is clicked"

Expected Behavior

When the clear button is clicked, it should invoke the update callback with empty arrays for both people and companies:

expect(mockUpdateCallback).toHaveBeenCalledWith({
  people: [],
  companies: [],
});

Actual Behavior

The callback is not being invoked at all (Number of calls: 0).

Potential Root Cause

The clear button click handler in CompactFiltersComponent may not be properly wired up to invoke the callback function.

Priority

Medium - This is a UI functionality issue that affects the ability to clear assignee filters in the compact view.
