Improve UI for password input (in general, but specifically for long passwords)

[FilipHarald]

Currently, when the password length reaches the max input length there is no visual indication when you type more characters.

As a fat-finger person myself and with a long password this can be just a liiiitle bit annoying.

I personally think only displaying input key strokes is the best way to go, i.e. no chars at all, but I can understand if others feel differently. A quick googling only gave me an example with i3-lock. But hyprlock has the same capabilities.

Anyway, just adding a simple animation to the input-field at least solves the problem of visual feedback.
