Same fix as hyprdrive's kitty (6c07c10): the 16 ANSI colors were still
stock template defaults clashing with the violet/crimson palette used
everywhere else in the suite. Fill them in from colors.conf plus a
few new neon tints in the same hue family, set background to the
real #1A1A1A instead of pure black, add matching border/bell/mark
colors, and drop the stale cursor-color pair in kitty.conf that the
theme include was silently overriding anyway.
