fix(hypr): correct invalid window-rule syntax in pip/retroarch/steam/system

Booting the VM peeled back two more layers of Hyprland config errors after
the geforce/moonlight fix:

  * pip.conf used underscored rule names with stray values —
    `keep_aspect_ratio on` and `border_size 0`. Hyprland's rules are
    `keepaspectratio` (boolean, no value) and `bordersize 0`.
  * retroarch/steam/system.conf wrote `idleinhibit, <mode>` with a comma,
    so Hyprland read <mode> as a selector ("Invalid value: always/
    fullscreen"). The mode is space-separated: `idleinhibit always`.

Verified clean in a rebuilt VM — the boot-time config-error overlay is
gone. All Omarchy-era rule-syntax holdovers, exposed once Component 5
wired apps.conf to source every app rule file.
