fix: patient language field silently dropped by stale browser-side validation schema

packages/db/usedSchemas/browser.ts (the browser-resolved copy of the Patient
zod schema, kept separate from the Node copy since it can't import
Prisma-generated code) was missing several fields added to the real schema
over time — preferredLanguage, gender, insuranceProvider, insuranceId,
groupNumber, policyHolder, and the PLAN_NOT_ACCEPTED status. Since the schema
isn't strict, those fields were silently stripped from every patient
create/update in the browser with no validation error, so edits to them
never reached the server.

Also fixes the AI call greeting always playing in English regardless of the
patient's preferred language — the greeting text was a single hardcoded
string, unlike every later turn in the conversation which already branched
by language.
