feat: add local PeeringDB SQLite integration via peeringdb-py

- Install better-sqlite3 for zero-latency local queries
- queryPeeringDBLocal() handles all major PDB API paths locally:
  /net?asn=X, /netixlan, /netfac, /fac?id__in=, /ixfac, /ix, /ixlan
- fetchPeeringDB() now tries local SQLite first, falls back to live API
- Eliminates rate limits and reduces P99 response times dramatically
- Local DB synced daily at 03:48 via peeringdb-py cron on Erik
- Graceful fallback: if SQLite missing/corrupt, live API used transparently
