Fix 9 seam-review findings

- Pinned target's profitability flag now overrides the extractor's bucket guess
- Extractor/target periods canonicalized so ledger forecast chaining matches
- autoRunOnDrop no longer error-loops on ungradeable inbox content; failed
  batches count as seen
- Ship 2 default graders (pipeline requires >=2 valid reports per deck)
- UI styles 'failed' deck chips as errors; .markdown discoverable
- Unknown adjudicator model disables adjudication loudly instead of silently
- Reserved rids extractor/adjudicator; teardown also clears bm-grader-* containers
