## Issue
Fixes 4524 `[mobile] in channel search not available`
## Changes
There are currently 3 wunderbars: (1) header (2) channel list (3) downloaded list.
The additional `wrapperStyle` in the header made it hard to find a solution that works for all 3, so I split 2 and 3 into `wunderbar__input--inline`.
## Issue:
Currently, the checkbox grayed-out state is only correctly updated when changing from "no-file" to "file selected". If you have selected a video file and later changed to a text file, the checkbox doesn't gray out.
## Code Changes:
`fileVid` wasn't being updated for the case of non-videos; now it does.
## Issue
Closes 3964 `Add Youtuber info to file page`
## Changes
(1) Refactor the YT-info query into `YoutubeBadge` component.
(2) For the File Page case, don't show "- last sync <date>" since the date has nothing to do with the file.
## Test
[x] YT Channel page
[x] YT Channel's claim page
[x] Non YT Channel page
[x] Non YT Channel's claim page
[x] No channel (anonymous) claim page
[x] Various RENDER_MODES
## Issue
Closes 4501 `Font size`
## New behavior
The Desktop app can now zoom the same way as browsers:
- Zoom In: "Ctrl+=" or "Ctrl+numpadPlus" or "Ctrl+WheelUp"
- Zoom Out: "Ctrl+-" or "Ctrl+numpadMinus" or "Ctrl+WheelDown"
- Zoom Reset: "Ctrl+0" or "Ctrl+numpad0"
## Code changes
(1) Electron provides this functionality through the `zoomIn|zoomOut|resetZoom` roles in the Menu, so it would have been a quick job.
However, given that Electron currently does not support having multiple accelerators for one item, we can't add `Ctrl+WheelUp` to the mix and would have to implement our own handler and use `webFrame`.
Given that we need to add code anyways, we handle both keyboard and mouse cases through the same handler, hence the existence of `zoomWindow.js`. It also provides the opportunity to few a few quirks with Electron's default implementation (e.g. stuck at both extremes)
(2) I recall there is another Issue for adding keyboard shortcuts. Given that these shortcuts are universally used in browsers, they are probably "reserved", so shouldn't clash with that task.
## Issue
Fixes 2675 `Claim search with exactly 20 results keep fetching next page`
## Changes
Use `claimSearchResultLastPageReached` (I didn't know it existed back then).
The unnecessary "loading" refresh will still happen one time, but at least now it doesn't happen every time we scroll to the bottom (and incorrectly incrementing 'page').
This is a follow-up on PR-4392.
## Issue:
The previous PR covered "pop from within the same page but with different query/order", but missed "pop after entering a claim".
1. Click `Your Tags`.
2. Set order to `New`.
3. Restart app or reload (crucial step)
4. Click `Your Tags`.
5. Click any claim.
6. `Back`. The order incorrectly resets to `Trending` -- it should stay at `New`.
