Add omarchy display text size to scale text everywhere
One knob for apparent text size, anchored to the 12px shell default: it sets the shell font base-size (~/.config/omarchy/shell.toml), GNOME/GTK's text-scaling-factor (12px -> 1.0), and the terminal font point size (12px -> 9pt) in lockstep. Accepts 9-20px; reset returns all three to default. Terminals live-reload where they can (alacritty/kitty/ghostty); foot gets a single restart nudge that replaces itself instead of stacking.
