fix(jira,tests): clarify manager-resolved disputes in Jira and the Summary tab

The validated/rejected Jira comment always said 'by both leads' and
never carried the manager's own notes, even when a manager had just
overridden two disagreeing votes — misleading, since that combination
of statuses is only reachable via a manager decision. Now detected
from the disagreement itself and worded accordingly, with the
manager's notes included via the existing extra-data mechanism.

Also reworks the Summary tab: Final Result moves to the top (was the
very last thing on the page) and now shows Containment alongside
Detection — previously the only place Containment appeared at all was
inside the editable Blue tab. Both team cards now show the validating
lead's notes, not just the approved/rejected badge, and flag when a
manager's decision resolved a disagreement between the two leads.
