fix(medications): purple dose accent shared across all medication kinds

The generic medication card surfaces the upcoming schedule dose with
a `font-medium text-purple-400` accent so titration overrides on the
schedule visually pop out of the muted next-intake line. The GLP-1
card omitted the accent entirely.

Mirror the same accent on the GLP-1 card so the only difference
between Mounjaro and Ramipril detail surfaces is the data being
shown, not the styling treatment. The schedule.dose still rides
inside the existing next-injection paragraph (hidden below sm: like
the generic card so the narrow-viewport row stays one line).
