This commit replaces all unnecessarily repeated code for decoding and
embedding blurhash canvases with separate component - <Blurhash>.

Under the hood Blurhash component will use effect dependent on its
props. This gives a few benefits: it will only be re-rendered whenever
the hash or width/height/dummy props update, and will not render if
canvas won't get to the final DOM, because then effect won't fire,
which prevents weird bugs like #14257.

This commit introduces new utility component - ShortNumber. It should
work almost the same way as original shortNumberFormat function,
though it also localizes units and accepts one more prop - renderer.

Renderer is a function that takes rendered short formatted number
and also ready-to-pluralize number to format display result accordingly.
Ready-to-pluralize number allows to correctly select plural for
compactly notated numbers, respecting thousands and other units.

Issue #12451 accurately describes the issue with using raw numbers
when replacing counter with short version. In short, it doesn't work
with languages such as Russian, that require different plurals,
according to the unit number was compacted to.

All previous usages of shortNumberFormat were replaced with new
function, and as it became unused, it was removed to avoid misleading.

* Refactor list of emoji requiring added outlines so that it can be theme-specific

* Use preview card blurhash in WebUI

* Handle sensitive preview cards

* Periodically save timeline markers

This saves timeline markers immediately upon message arrival, but not more
than once every 5 minutes.

This does not change how the markers are saved on closing the window,
except that it avoids submitting them if there is no need for it.

* Use the Fetch API when possible instead of XHR on window unload

Otherwise, it may mislead users into believing this setting is an
exception to the muting behavior.
