theme: Catppuccin Mocha blue/pink variant of the Persona rice

Keeps the Takemi geometry — the lean, the chamfer, the slabs — and swaps
the palette wholesale. Mocha carries the ground; blue is the accent for
anything live (focus, selection, borders, hover) and pink is the alarm
for anything destructive or failed, so one hue no longer has to mean
both 'active' and 'wrong'.

Destructive controls rest as a pink keyline and fill solid only when
hovered or selected: Mocha's pink is a pastel, and a resting slab of it
reads as washed-out red rather than as a warning. The load ramp climbs
text -> blue -> pink for the same reason, instead of fading straight
through a muddy mid-tone.

Surfaces covered: quickshell, Hyprland borders, alacritty, fish, dunst,
and nvim (via the catppuccin plugin, submodule branch catppuccin-mocha).
GTK 3/4, Qt and xsettingsd move to catppuccin-mocha-blue and are now
tracked, since nothing else makes non-shell apps match the rice; the
previous Takemi copies are in theme-repair-backups/.
