New Experiments section in the rail: lists tracking experiment rules
(status, traffic, arms, targeting), shows this session's assignment via
evaluate-experiments, per-arm analytics with winner/significance, a QA
arm override (sets the storefront variant cookie), and a two-step
pause/resume kill-switch. Admin reads degrade when the tracking gate
refuses; eligibility always works. Mock tracking endpoints + harness
tests.
