Fix error typing
Error type is unknown in catch blocks even though we control the throwing functions. Give errors a proper type.

Ref: #76155 (comment)

I’m not sure what the best way to handle this is. try/catch returns a variable typed as unknown, which cannot be typecast. I think the current approach is fine, but I’m open to making changes if there’s a better solution.

@andrewserong, @aagam-shah would appreciate your review on this PR when you get a chance

@im3dabasia Thanks for the refactoring — the typed store object change is a solid improvement.

A few things:

1. Keep ACTIONS.map() pattern — I agree with @aswasif007's suggestion. Combine it with your new ActionItem component. Define the array inside the component so handlers are in scope, and spread props: <ActionItem key={ action.slug } { ...action } />. This also eliminates the old buttonProps lookup.

2. Leftover @ts-ignore comments — a few remain that are likely unnecessary now (e.g., api.ts:51 has @ts-ignore on dispatch(coreContentGuidelinesStore) but the identical call in fetchContentGuidelines works without it; same for guideline-accordion-form.tsx:33,41). Worth testing removal.

3. Fix lint failures.

@aagam-shah, I’m done addressing the feedback. I’d appreciate your review once you’re back.

I’ll go ahead with the merge. I rebased the PR to check if the failing tests would pass, though they seem unrelated.
