fix: complete rate limiter integration and report command structure

- Add RequestRateLimiter class to providers/base.py with wait() method
- Integrate rate limiter through enrichment pipeline (enrich_identities_data → _enrich_record_with_fresh_providers → _build_providers → TMDBProvider)
- Add _cmd wrapper functions to commands/report.py for CLI imports
- Fix SeriesIdentity import in reports.py
- Add sidecar file tracking to planner review_context for move operations
- Update tests to match new rate limiter signature
