Expanded homepage pins to support 2 types of input (if both are passed in, pinnedUrls take precedence):
(1) pinnedUrls --> uses doResolveUris (resolve)
(2) pinnedClaimIds --> uses doResolveClaimIds (claim_search)
Instead of injecting the pinned URLs directly, we inject from `resolvedPinUris`, which will be blank until the uris are resolved, thus preventing it from being resolved individually from the tiles.
There's additional complexity with the `claim_search` method, as the rest of the code deals with uris instead of IDs. Fortunately, it's all contained with `useResolvePins`, so removal would be easier when the batch `resolve` issue is fixed.
