Add dark-mode rules for `.termin-type-chip.termin-type-XYZ`. Without them
the chip inherited the bare `.termin-type-XYZ` swatch rule (line 8407+),
which intentionally paints text the same colour as the background for
the dot/border-left swatch use case → text invisible in the chip context.
Mirror the existing badge dark rules (lines 8413-8415) so chip and badge
share the same colour family. Adds the missing `consultation` variant for
the chip (badge consultation dark is also missing but out of scope).
