feat: store raw processor tree JSON and add error categorization fields

Fixes iteration overlay corruption caused by flat storage collapsing
duplicate processorIds across loop iterations.

Server:
- Store raw processor tree as processors_json JSONB on executions table
- Detail endpoint serves from processors_json (faithful tree), falls back
  to flat record reconstruction for older executions
- V10 migration: processors_json, error categorization (errorType,
  errorCategory, rootCauseType, rootCauseMessage), OTel (traceId, spanId),
  circuit breaker (circuitBreakerState, fallbackTriggered), drops
  erroneous splitDepth/loopDepth columns
- Add all new fields through full ingestion/storage/API chain

UI:
- Fix overlay wrapper filtering: check wrapper type before status filter
- Add new fields to schema.d.ts
