Follow-up to #17/#19. After a restart the exporter's window started empty, so authors who had not sealed a block since had no author label series (and no timing caps) until they authored again. On the leaderboard that showed as blank author cells for the smaller miners, and the #19 range fallback could not help because the label metric did not exist before 06:45 today.

The first poll now fills the window from chain history: 3600 blocks in 15 s against bob. Window only: the authored counter is untouched so increase() sees no phantom burst, and no tip timing is observed for blocks not watched arriving. Capped at 180 s of wall clock. Locally the three authors that were blank on the dashboard (0x2f7730…, 0xcc5c9b…, 0x435ca0…) get their abbreviated label immediately after start.

The leaderboard's top-20 also drops rows with zero blocks in the range; those were stale series with nothing to show and could never carry a label.

arena: backfill the rolling window from chain history at startup; leaderboard hides zero-block rows 3d69374c26

After a restart the window started empty, so authors who had not sealed a
block since had no leaderboard row source, no author label series and no
timing caps until they authored again; on the dashboard that showed as
blank author cells for the smaller miners. The first poll now fills the
window (3600 blocks, 15 s against bob) from chain history, window only:
the authored counter is untouched so increase() sees no phantom burst, and
no tip timing is observed for blocks not watched arriving. Capped at 180 s
of wall clock.

The leaderboard's top-20 also drops rows with zero blocks in the range;
they were stale series with nothing to show.
