Remove test.fail annotation from AC-21.6 "Apply from modal includes
tactic in result". GET /api/mitre/matrix now returns tactic_id in TA-format
("TA0007") so the PATCH succeeds and the tactic chip appears.
Update button selector in both AC-21.6 tests from title*="discovery"
to title*="TA0007" to match the fixed matrix response format.
Suite: 158 passed, 0 failed.
