fix(tooltip): use unique 'hint-experts' key for program rating hint

Even with isolated DI instances, using the same 'base' key as the
analytics button (DeatilComponent) could still conflict. Replace with
a dedicated TooltipKey so the hint tooltip state is never reachable
from any other component regardless of DI scope.

- Add 'hint-experts' to TooltipKey union
- Replace 'base' with 'hint-experts' in list.component.html and openHintModal
