Redesign the inline detail panel from a single left-aligned column
to a two-column layout that uses the full panel width.
Left column (55%): latency chart, min/avg/max stats, 30-day
uptime timeline.
Right column (45%): status/latency/last-check summary, type-
specific metadata (HTTP response code + SSL expiry, ping hostname,
port target, push interval/last heartbeat, DNS resolver), uptime
percentage + retry count, and up to 5 state changes listed
vertically with error reasons.
Narrow terminals (<80 cols) fall back to the original stacked
single-column layout.
