Kpa-clawbot 0e286d85fd fix: channel query performance — add channel_hash column, SQL-level filtering (#762) (#763) ...

## Problem
Channel API endpoints scan entire DB — 2.4s for channel list, 30s for
messages.

## Fix
- Added `channel_hash` column to transmissions (populated on ingest,
backfilled on startup)
- `GetChannels()` rewrites to GROUP BY channel_hash (one row per channel
vs scanning every packet)
- `GetChannelMessages()` filters by channel_hash at SQL level with
proper LIMIT/OFFSET
- 60s cache for channel list
- Index: `idx_tx_channel_hash` for fast lookups

Expected: 2.4s → <100ms for list, 30s → <500ms for messages.

Fixes #762
