## Issue
If you are already at the homepage and you click the "Home" or "Odysee" logo again, the entire page reloads, causing the whole startup sequence to re-run (lots of fetches).
This can be annoying when not intended (e.g. clicked too many times), as startup is slow for some and we also lose non-persistent Redux data (for debugging).
I believe the requirement was just to reload the homepage tiles, as they might be showing stale ones after a while. A full reload was the quick-and-easy fix.
## Approach
Best not to touch the complicated `ClaimTilesDiscover`, so just clear the search cache key in this scenario. `ClaimTilesDiscover` will then pick this up and perform a new `claim_search`.
## Root-cause?
It doesn't happen on the commit before the Theme change. However, it's possible that the y-pos is reset since we are indeed unmounting the dual list and re-mounting the single list.
Maybe the css got more efficient and we ended up painting more frames than before.
## Fix
Fix by stashing and restoring the the y-position during the expansion.

## Change
- Header: Use the "channel list undefined" instead of "active channel url undefined" to determine if the button should be "pending".
- App: restore the use of `activeChannelClaim` instead of `activeChannelId`. In the existing design, the latter is never cleared is some situations, so the former is more accurate as it takes the current channel list into account. We might want to hide (not export) `activeChannelId` to avoid this mis-use again.
## Issue
When loading the homepage, I kept seeing a blank page with footer first. Even Google is picking it up.
## Ticket
572 Slow appearance of tiles
## Notes
The tiles were originally delayed to prevent the "Upcoming Livestream" section from causing layout shifts.
With the new theme, the footer would cause a visible shift anyway. Hiding the footer is one solution, but I think not showing anything until the fetch is done is bad because the livestream fetch could stall.
## Why
The playing URI was being cleared every time we leave the File Page, I believe to prevent the floating from continue playing outside of the File Page.
## Approach
Close FileRenderMobile by checking playingUri/primaryURI instead.
For the case of livestreams, just display it.
These are now checked at client side (not CDN side), so not actually an error worth collecting.
Also removed "Uploading the same file from multiple tabs or windows is not allowed." -- no longer exists.
## Issue
534 prevent new channel creation over x channels
## Notes
Also handled from the API call (`doCreateChannel`) in case there are other UI components that create channels.
- Marked optional props properly.
- Re-ordered to make it easier to differentiate "props used in jsx" vs. "from redux".
Separated the commit to make the upcoming diffs easier to read.
