Simplified the CSS for issue boards

## What does this MR do?

It gained a lot of extra cruft through the different improvements etc. This removes a lot of the stuff which would hopefully also speed up the browser rendering.

- Removed flexbox from a lot of things which in turn reduces it's complexity.
- Removed styles that either aren't used or aren't needed.
- Various other improvements to the CSS.

Basically just improved the CSS by removing overly complex CSS. There are no visible changes to issue boards, just less CSS for the same results.

Fixed commit search UI

Replace contributions calendar timezone payload with dates

## What does this MR do?
Fixes a ~regression bug introduced in !5784 whereby the calendar squares would not render due to a timezone mismatch between the server timezone and the browser (user) timezone. I am now returning the dates instead of the timezone from the backend. There's a good chance we will still have a calendar off by one error (which is an existing issue #1943) but passing dates should make sure that the calendar activity squares render correctly across timezones.

## Are there points in the code the reviewer needs to double check?
Double check that this displays the correct calendar squares when the GitLab instance is hosted in a different timezone than the user viewing it

## Why was this MR needed?
Fixes ~regression issue 😞

Hides tooltip on discussion toggle button when clicking

## What does this MR do?

Hides the tooltip when clicking the discussion toggle button.

Rather than triggering the tooltip to hide we trigger blur. This is because of how _amazing_ Bootstraps tooltips are. They are shown also on focus so if we trigger the tooltip to hide & then mouseover the button again the tooltip still shows.

Fixed issue boards loading issues on large screens

## What does this MR do?

On larger screens it is possible for 20 issues to load (this is the amount per page) & there still to be room underneath the last issue which means the list can't scroll stopping the infinite scrolling working.

This MR checks if there are more issues to load, if there are & the height of the scroll area is less than or the same as scroll height then more issues are loaded. This will keep happening until it is possible to scroll, once it is possible to scroll it goes back to the default behaviour of the infinite scrolling.
