fix(wiki): fix progress display and reprocess feedback issues

Three root causes for broken progress:

1. JobStageBar was shown whenever a job record existed (even at queued
   stage), hiding the working SSE-driven progress bar. Fix: only show
   JobStageBar when job.stage !== queued.

2. SSE connection only opened when hasProcessing was true (status ===
   processing), but reprocess sets status to pending first. Fix:
   include pending in the hasProcessing check.

3. After reprocess, if processing finished before SSE connected, the
   status badge stayed on pending forever. Fix: immediately set local
   status to processing after reprocess API call, clear stale job
   entries, and add delayed re-fetches (5s/15s) as safety net.

Also: clear rawJobs entries on raw.completed/raw.failed SSE events to
prevent stale JobStageBar from lingering after processing ends.
