fix(ai): screen numberless halving and dose changes, and hold continuations to the plan

The outbound screen let a halving with no number through in every
language but Dutch ("Reduce your dose by half.", "Reduza a dose pela
metade.", "Tome meia dose."), let a bare change imperative through
("Zmniejsz dawkę.", "복용량을 늘리세요.") and did not know the Polish
spelling of the generic stems, so "Odstaw ramipryl." passed. Each
language's bank now carries a halving and fraction shape and a bare
change shape on a medication noun, and the stems include the Polish
-pryl, -statyn and -glutyd.

The continuation exemption trusted "as before" on any surface that
passed no schedule, so "Take 40 mg as before." went out to people who
had never taken 40 mg. The screen now takes the dose plan (each active
medication with its dose) instead of a bare list of numbers, and
exempts a stated amount only when it is the planned dose of the
medication the sentence names. Without a plan no stated amount is
exempt.
