Kpa-clawbot 8f712774ae fix: WS broadcast missing decoded fields + cache analytics endpoints ...

#156: The Go WebSocket broadcast from IngestNewFromDB was missing the
'decoded' field (with header.payloadTypeName) that live.js needs to
display packet types. Added decoded object with payloadTypeName
resolution, plus observer_id, observer_name, snr, rssi, path_json,
and observation_count fields to match the Node.js broadcast shape.

#157-160: Analytics endpoints (hash-sizes, topology, channels) were
recomputing everything on every request. Added:
- TTL caching (15s) for topology, hash-sizes, and channels endpoints
  (matching the existing RF cache pattern)
- Cached node list + prefix map shared across analytics (30s TTL)
- Lazy-cached parsed path JSON on StoreTx (parse once, read many)
- Cache invalidation on new data ingestion
- Global payloadTypeNames map (avoids per-call allocation)

Fixes #156, fixes #157, fixes #158, fixes #159, fixes #160
