Re Extract Strategy

Re-trigger structured-pillar extraction for an approved strategy.

Looks up the team’s most-recent approved CycleInstance, then schedules team_service._extract_orchestrator_config for that cycle. Returns immediately — extraction runs in the background and writes either orchestrator_config_extracted or strategy_extraction_failed to team_audit_log.

Operator workflow:

1. POST to this endpoint.
2. Poll GET /teams/{id}/activity for the matching audit row.
3. On success, the next cycle_scheduler tick will pick up the enriched pillars; on failure, inspect the audit details for the truncation / parse error.
