Fix Hyprland 0.53 windowrule syntax breaking changes (#4025)

* Fix Hyprland 0.53 windowrule syntax breaking changes

Hyprland 0.53 introduced breaking changes to windowrule syntax:

- Props now use `match:` prefix: `class:pattern` → `match:class pattern`
- Boolean effects require `on` suffix: `float` → `float on`
- Snake_case naming: `nofocus` → `no_focus`, `stayfocused` → `stay_focused`
- `noborder` replaced with `border_size 0`
- `noanim` replaced with `animation none`
- layerrule syntax: `noanim, X` → `animation none, match:namespace X`
- `misc:new_window_takes_over_fullscreen` → `misc:on_focus_under_fullscreen`

See: https://github.com/hyprwm/hyprland-wiki/pull/1278

* Correct for the new style

* Migrate the scrolltouchpad setting in userland too

* Need a reboot to pair with new Hyprland
