fix(voice): hear "یادداشت" as a note request, and stop the note at the next instruction

Two reports from live dictation in fa.

The locale trigger vocabulary listed only verbs that ask for a note ("بنویس",
"یادداشت کن"). Naming the field itself — "توی یادداشت‌ها بنویس", "در توضیحات" —
reported no commentTrigger, and the resolver discards a comment without one, so
the note was silently dropped. Added the field-name shape to fa, en and nl.

Where the dictated note ends was never stated, so the model answered it
inconsistently: "توی توضیحات بنویس سلام چطوری و بفرست برای لابراتوآر سانشاین"
sometimes put the lab dispatch inside the comment. Added a no-overlap rule — a
clause reported as a lab, tooth, prosthesis or deadline is an instruction and
must not appear in comment as well — with that sentence as a worked example.

Both rules go in the prompt and in the JSON-schema field descriptions, because
the schema description is what the model reads while filling the field. No code
enforcement for the second: stripping an extracted clause out of free-speech
note text by string matching is guesswork, and the review sheet shows the note
before it is saved.
