Subject: feat: theme dunst in Macchiato with a wallpaper-driven accent frame

Notifications previously drew their colours from the pywal preset, so they were
pure black on white and did not match anything else. Structural colours are now
fixed Macchiato, with the accent as the frame on normal urgency, a muted
surface frame on low, and Macchiato red on critical. Font moves to Noto Sans to
match the rest of the desktop.

udt-accent substitutes the accent after pywal renders the template, then
restarts dunst so it rereads the file. It restarts rather than just killing:
nothing else respawns dunst, and a dead dunst means no notifications at all.

Also fixes a dangling reference: the template pointed dunst's dmenu at
darknix/main.rasi, a theme that no longer exists.

The template is tracked here as templates/dunstrc; the live copy is
~/.config/wal/templates/dunstrc.
