webui: Make the Web UI more accessible for blind users

[domasofan]

Hi,

The llama.cpp server web ui recently received a big update.
Maybe someone has some time to make the web ui more accessible (WCAG 2.2 compliant).
Especially labeling the buttons.
It seems that the buttons labels seem to be above the buttons.
At least that it is what i am seeing from a blind users perspective.

Greetings and thanks,
Simon

Hi @domasofan thanks for reporting. Normally I pay attention to the accessibility, it just that currently I quite run out of time to perfect it.

Will put a bit more priority on this.
