Three fixes in response to user feedback:
1. Span input disappearing on End/Fail
The Upsert's DoUpdates always listed input/output/metadata, so calls
that only set output (EndSpan) or only set error_* (FailSpan) wrote
NULL into input/metadata, clobbering whatever Begin had recorded.
Build the column list dynamically: skip input/output/metadata when
the incoming row's value is nil. nil now means "preserve existing"
(matches user's intuition "Begin recorded it, End shouldn't erase it").
2. Subspans not auto-expanded
Stages with children (multimodal.image[*], postprocess.summary,
postprocess.question, postprocess.graph.chunk[*]) required a click
on the ▸ caret to surface — easy to miss. On the FIRST successful
fetch per (knowledgeId × attempt), auto-expand any stage that has
children. Subsequent polls honor whatever the user has collapsed,
so manual collapse mid-parse stays collapsed.
3. Auto-poll still not firing
Force-arm the polling interval in onMounted regardless of state.
The per-tick callback decides whether to actually fetch based on
current parse_status — so the loop can never get stranded waiting
on a status transition that already happened. Added a console.debug
when the interval arms, so we can verify from DevTools console that
polling is actually running.
