Improve icons in editing mode

[766F6964]

I noticed that the icons in the markdown editing mode are slightly blurry.
This is especially noticable when zoomed in.
Below is an example with high zoom level to illustrate this:

It is worth noting, that icons in e.g. the main menu in the top right corner don't have this problem.
I think it would make sense to replace this icons with .svg icons to have them sharp on any zoom level.
Additionally, this might be a good opportunity to go for a uniform icon style in the application.

Unfortunately these icons are part of the 3rd party (Toast UI) markdown editor that flatnotes uses and therefore are not easily replaced.

Really I'd like to replace the entire toolbar to something more in keeping with the rest of the app but that would be a bigger job.

@dullage is there value in @766F6964 opening an issue upstream https://github.com/nhn/tui.editor ?

@clach04 - I don't think so. The editor may even allow me to build my own toolbar already, but I haven't looked through the docs recently.

To be honest, rather than doubling down on the Toast Editor, if I were to change anything I'm more likely to look at other options. Something headless with good maintenance. Project for the future though.
