fix: exponential backoff for idle crawler workers

An idle worker re-issued a row-locking lease query every 1s per worker with
no backoff. Replace the flat sleep with idle_backoff: 1s, 2s, 4s, … capped at
30s, reset to 0 the moment a job is leased, so a quiet daemon stops hammering
the crawler_jobs table.
