Operator setting up auto-update was forced to scroll down to the
"Manifest actuel" card and find the global Sync button after each step
of the launcher workflow. Add a dedicated "🔁 Recalculer hash + signer"
primary-blue button right inside the launcher card. It posts the same
action='sync' so behavior is identical — it's just discoverable from
where the operator is looking.
