Restore keyboard layout after hyprland config refresh (#5319)

omarchy-refresh-hyprland overwrites input.conf with the default
template, which has kb_layout and kb_variant commented out. Non-US
users lose their keyboard layout with no obvious recovery path.

Re-run detect-keyboard-layout.sh after the refresh so the system
layout from /etc/vconsole.conf is re-applied, matching what the
initial install does.

Closes #2507
