An admin whose report delivery is stuck (old schema, network issue,
etc.) saw the v5-upgrade and portal buttons greyed out with no
indication why, or what to do about it — the backend's single-packet-
in-flight guard is correct, but silent. Add an inline note pointing at
"Retry / send if due" when a pending packet is the actual cause.
Also: "Review expanded usage.v5 scope" didn't read as an upgrade
action — renamed to "Upgrade to usage.v5" / "Auf usage.v5 upgraden".
"Open usage portal" is now a primary (green) button in both its
signed-in and pre-participation forms, matching the visual weight of
the other primary actions on this tab instead of blending in as a
secondary outline button.
