1. Chat input toolbar was clipped in the empty state: the form's overflow-hidden
made its flex min-height resolve to 0, so the vertically-centered layout
squeezed it and hid the bottom toolbar (attach/add-patient/model/mic/send).
Add `shrink-0` to the form; let the empty-state column scroll.
2. AI-imported appointments now create/link a patient: services.ensurePatient
reuses a same-name patient or creates one (auto file number, source "ai");
appointments.createAppointment calls it when the booking has no file number,
so imported people appear on the Patients page.
3. Many proposals collapse into one BatchActionPreviewCard → a review dialog
with per-row remove and "Add all" (commits sequentially), instead of one
Add/Discard card per record.
Plus: widen the Live chart right margin so the value pill stays inside the card.
Verified with `next build`.
