feat(shared): one faded glow for hovers across the shells

Hover and attention effects were solid: a flat accent ring round the
user page's avatar, a flat quarter-disc in the hot corner, and thick
accent or white borders on window cards, keycaps and knobs. Glow.qml
is a RectangularShadow in the accent, fading out from the shape's edge
and in over 140ms, linked into desktop, window-switcher and keybinds
like Theme.qml, and all five places use it. Selection borders in the
appearance tabs stay: they mark state, not hover.

The avatar also gains the hover cue in the first place: the hand
cursor never showed under a hyprcursor-only theme, so without it the
picture gave no sign it could be clicked.
