Adds timezone to the HouseholdSettings client type and a Timezone field (text input with a datalist of common IANA zones) to the Preferences form. Save validates the value as UTC or an Area/Location name and patches it only when changed. When the loaded timezone is empty, the screen patches the browser's Intl zone once before showing the form, so nothing the admin enters can be overwritten; a missing or unusable zone leaves the field empty.
