test(integration): user testing validation round 3 — 12/12 assertions passed

VAL-CROSS-003 re-tested after FEAT-009-FIX-002 fixes:
- Run history now displays all 3 validation runs (not just latest)
- Coverage bar tooltip shows '0 of 3' (not 'undefined of 3')

All 12 integration milestone assertions now pass.
