feat: Keyboard support & proper labeling of things

[Freeplayg]

Summary

Am not sure if this should count as a bug or feature, but having keyboard support, as well as properly labeling buttons for screen readers should be a needed thing.

I know one way most of the labeling was done in Firefish was setting the aria-label attribute in the script that adds the tooltips, so that should make that bit easier. Some cherry-picking could also probably be done for especially the form components i think? I hope I didn't make those commits too messy, I'll try to find them later
Edit: This should be the commit for the form inputs in Calckey: https://codeberg.org/firefish/firefish/commit/1cc7c3f8dd685cc0ec62d55b0bdaf32c0475735c (https://codeberg.org/firefish/firefish/pulls/10130/files)
I hope that not much has changed in misskey's input components ?

Buttons should also have an outline shown when they're focused

There's a bunch more stuff that would need to be done, but that's the most basic stuff to make it at least sort of usable. Am still learning this stuff also

"but having keyboard support" don't really what is meant with this as you can scroll using the keyboard as well as switch light/dark mode, open new post dialog

keyboard support as in being able to tab through every button, basic accessibility (edit: Try navigating without a mouse at all.)

There's more to it than that, i just only really know how to explain the bare minimum lol
