The service picker summed duration_minutes itself while the backend already
returns total_duration_minutes. Two sources of truth: when the formula changes to
solo/additional minutes, the site would keep showing the old number and the
patient would see a duration that does not match their appointment.
The picker runs before the date step and appointment-service-slots needs a date,
so it is called with today. total_duration_minutes does not depend on the date —
the backend computes it before touching that day's shifts, so the number is right
even when today is closed and start_times comes back empty.
The label reads "مدت تقریبی" until the server number arrives, then "مدت کل".
A missing field or a failed request falls back to the client sum with a
console.warn rather than blanking the step.
Staleness is derived from the selection key instead of reset in the effect body,
which also clears the set-state-in-effect lint warning.
