Kpa-clawbot 42afbb1398 perf(go): switch channels + RF analytics to in-memory store
Replace SQLite-backed handlers for /api/channels, /api/channels/:hash/messages,
/api/analytics/rf, and /api/analytics/channels with in-memory PacketStore queries.

Before (SQLite via packets_v VIEW on 1.2M rows):
  /api/channels              7.2s
  /api/channels/:hash/msgs   8.2s
  /api/analytics/rf           4.2s

After (in-memory scan of ~50K transmissions):
  Target: all under 100ms

Three new PacketStore methods:
- GetChannels(region) — filters payload_type 5 + decoded type CHAN
- GetChannelMessages(hash, limit, offset) — deduplicates by sender+hash
- GetAnalyticsRF(region) — full RF stats with histograms, scatter, per-type SNR

All handlers fall back to DB queries when store is nil (test compat).
