Livestream category improvements (#7115)
*  Remove old method of displaying active livestreams

Completely remove it for now to make the commit deltas clearer.
We'll replace it with the new method at the end.

* Fetch and store active-livestream info in redux

* Tiles can now query active-livestream state from redux instead of getting from parent.

*  ClaimTilesDiscover: revert and cleanup

## Simplify
- Simplify to just `uris` instead of having multiple arrays (`uris`, `modifiedUris`, `prevUris`)
- The `prevUris` is for CLS prevention. With this removal, the CLS issue is back, but we'll handle it differently later.
- Temporarily disable the view-count fetching. Code is left there so that I don't forget.

## Fix
- `shouldPerformSearch` was never true when `prefixUris` is present. Corrected the logic.
- Aside: prefix and pin is so similar in function. Hm ....

* ClaimTilesDiscover: factor out options

## Change
Move the `option` code outside and passed in as a pre-calculated prop.

## Reason
To skip rendering while waiting for `claim_search`, we need to add `React.memo(areEqual)`. However, the flag that determines if we are fetching `claim_search` (fetchingClaimSearchByQuery[]) depends on the derived options as the key.

Instead of calculating `options` twice, we moved it to the props so both sides can use it.

It also makes the component a bit more readable.

The downside is that the prop-passing might not be clear.

* ClaimTilesDiscover: reduce ~17 renders at startup to just 2.

* ClaimTilesDiscover: fill with placeholder while waiting for claim_search

## Issue
Livestream claims are fetched seperately, so they might already exists. While claim_search is running, the list only consists of livestreams (collapsed).

## Fix
Fill up the space with placeholders to prevent layout shift.

* Add 'useFetchViewCount' to handle fetching from lists

This effect also stashes fetched uris, so that we won't re-fetch the same uris during the same instance (e.g. during infinite scroll).

*  ClaimListDiscover: revert and cleanup

## Revert
- Removed the 'finalUris' stuff that was meant to "pause" visual changes when fetching. I think it'll be cleaner to use React.memo to achieve that.

## Alterations
- Added `renderUri` to make it clear which array that this component will render.
- Re-do the way we fetch view counts now that 'finalUris' is gone. Not the best method, but at least correct for now.

* ClaimListDiscover: add prefixUris, similar to ClaimTilesDiscover

This will be initially used to append livestreams at the top.

*  Re-enable active livestream tiles using the new method

* doFetchActiveLivestreams: add interval check

- Added a default minimum of 5 minutes between fetches. Clients can bypass this through `forceFetch` if needed.

* doFetchActiveLivestreams: add option check

We'll need to support different 'orderBy', so adding an "options check" when determining if we just made the same fetch.

* WildWest: limit livestream tiles + add ability to show more

Most likely this behavior will change in the future, so we'll leave `ClaimListDiscover` untouched and handle the logic at the page level.

This solution uses 2 `ClaimListDiscover` -- if the reduced livestream list is visible, it handles the header; else the normal list handles the header.

* Use better tile-count on larger screens.

Used the same method as how the homepage does it.
