iris 8b8a322369 grafana dashboards: shorten panel descriptions
Cut every panel/board description down to a short statement of what the
number is. Drops the design-reasoning prose, edge-case notes, and
operator-attributed quotes that had accumulated in an earlier pass —
useful context while building the boards, wrong shape for a tooltip an
operator glances at mid-incident.
