[style] Add animated text glow on hover to settings menu items

[NextDev65]

Implement an animated text glow effect when hovering over the labels in the settings menu, in the style of Material Design 3 (MD3).

The effect should be applied to the .toggle-label and use text-shadow for the glow.

The animation should be enabled or disabled based on the user's animation settings.

Sample CSS:

.toggle-label:hover {
    color: #fff;
    text-shadow:
    0 0 7px #fff,
        0 0 10px #fff,
            0 0 21px #fff,
                0 0 42px #0fa,
                    0 0 82px #0fa,
                        0 0 92px #0fa,
                            0 0 102px #0fa,
                                0 0 151px #0fa;
   text-shadow: rgba(255,162,0,1) 0px 0px 10px;
}
