Description

This updates the Promo Queue framework to respect a promo's timeout when force-showing a promo from the debug menu. This force-show debug action allows the promo UI to be viewed separately from the promo queue (e.g. triggers, cooldowns), promo eligibility criteria, and other side effects.

Now, the promo's timeout is respected so the debug action better reflects real promo UI (including auto-dismiss) without having to manually enforce the timeout.

Testing Steps

1. Debug menu → Promo Queue → autoplay-discoverability → Force Show.
2. Confirm the Autoplay Discoverability promo is displayed (a popover on the permission center in the address bar).
3. Wait for 5 seconds and confirm the promo is auto-dismissed.
4. Debug menu → Promo Queue → autoplay-discoverability → Force Show.
5. When the Autoplay Discoverability promo appears, hover the mouse over the popover and confirm it isn't auto-dismissed (matches production behavior).

Impact

Low: Behavior change is limited to debug action (internal tooling)

Note

Low Risk
Changes are centered on debug force-show and session bookkeeping; production promo evaluation and history updates are unchanged except removing a redundant custom timeout that matched the feature-tip default.

Overview
Debug Force Show in the Promo Queue menu now runs promos through the same PromoService active-session path as production shows, so timeouts, eligibility retraction, and promo conflicts behave like a real show instead of a one-off delegate call with a manual sleep.

Force-show sessions are tagged with isForceShow: they skip writing lastShown, cooldown/dismissal history, and applyResult on any outcome, while still driving hide() and timeout handling via PromoType.timeoutInterval.

For autoplay discoverability, the delegate no longer owns a 5s displayDuration or sleeps on force show; it presents the permission center and awaits the continuation until the service times out or cleans up. PromoType(.featureTip) still uses the default 5s feature-tip timeout. Force show also skips the shown pixel.
