Changes to Read-only convert-to-invoice readiness for an appointment estimate. Converting is the last step before payment, so the gate blocks while any line is still Pending or a performed take-home label hasn't been filled. Drives the Convert button's disabled state + blockers popover (mirrors the BillableItem availability pre-check). Hospital sheets retain these execution gates even without an appointment billing association; standalone quotes are exempt — the quote itself becomes the bill.
