fix(medications): render intake datetime fields through the format-aware picker

The three intake dialogs (log, edit, dose-history add) still used a raw
datetime-local input, so they ignored the user's date-format preference.
Route them through DateTimeField like every other date surface. Also
correct a stale diastolic-floor comment in the dashboard verdict.
