Restructure the current-job card around the question the monitor exists to
answer: time remaining is now the hero, with percent riding the bar. Add a
client-side throughput sparkline (90 s rolling buffer of encode speed against
a fixed 1.0x realtime reference) and a health-colored speed gauge so stalls
and sub-realtime encoding are visible at a glance. Collapse the repetitive
input queue into a count plus shared-prefix rows.
