Add auto-heal pipeline command and fix multi-source draft processing

- Add `ietf auto` command: fetches, analyzes, embeds, extracts ideas,
  and refreshes gaps across all sources with cost-based auto-approval
- Fix SourceDocument→Draft conversion in auto fetch step
- Fix gap_analysis method name in auto command
- Process all 270 unrated ETSI/ISO/ITU/NIST drafts (761 total, all rated)
- Update web UI templates and data layer for multi-source support
