It was being recalculated repeatedly.
This memoizes it, although it still re-calculates occasionally despite none of the source arrays changed. I think it is due to the state change in the Preference Sync.
Note: input selectors to `createSelector` needs to be extractions-only (i.e. must not have transformations). I think most of our `makeSelect*` selectors violate this and broke memoization.

## Changes
Pitfalls of pausing render via React.memo:
- We'll miss the `doClaimSearch()` since that is sparked by an `useEffect`.
Seems like we can't avoid having a redundant copy of the previously-displayed URIs.
* ❌ 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.
## Issue
3587 Show content view counts on channel pages
## Notes
Limited to just "channel pages" for now as specified in the ticket.
Can be enabled for all claim previews, as long as there's an efficient spot to run the batch fetching. Either make `fetchViewCount` prop default to true, or add the parameter in places that need it.
## Issue
GUI fix for 5979 `claim search runs twice sometimes and "refreshes" view`
The search query might encounter minor alterations after rendered (e.g. for the case of 5979, the `moderation.Blocklist` data came late). The code currently resets the result to 0 before initiating `claim_search`, so we see the GUI blink.
## Idea
There is a possibility that the query-change does not alter the final results in the end. Instead of reseting to the results to zero, hold on to the previous results until the fetch is done.
## Known issue
The tiles no longer blink if there is no change, but the "LIVE" indicator still does. I didn't want to propagate the info too deep, so leaving as is for now. It can be considered a feature ("blinking LIVE indicator" :))
## Results
- No blinking if results stay the same.
- Minimal tile-shifting if new ones are added or removed.
- In the current Odysee homepage, reduced React commits from 88 to 76 (save some CPU cycles).
Scenarios where active livestreams will not appear:
- creation date is way back.
- homepage section options excludes livestreams.
Make an explicit `claim_search` but with `has_no_source` if the client wants `liveLivestreamsFirst`.
If there are lots of channels with livestreams, there's a possibility that the final list will be larger than what was requested. We could trim it to be within the original `options.pageSize` range, but I left that out for now.
if blockedList takes a while to return, the app would call claim_search once without the blocked list, then again with the block list. just hide them in the ui
* initial support for block/mute
* hide blocked + muted content everywhere
* add info message for blocked/muted characteristics
* sort blocked list by most recent block first
* add 'blocked' message on channel page for channels that you have blocked
* cleanup
* delete unused files
* always pass mute/block list to claim_search on homepage
* PR cleanup
