Kpa-clawbotandyou 56115ee0a4 perf: use byNode index in QueryMultiNodePackets instead of full scan (#589) ...

## Summary

`QueryMultiNodePackets()` was scanning ALL packets with
`strings.Contains` on JSON blobs — O(packets × pubkeys × json_length).
With 30K+ packets and multiple pubkeys, this caused noticeable latency
on `/api/packets?nodes=...`.

## Fix

Replace the full scan with lookups into the existing `byNode` index,
which already maps pubkeys to their transmissions. Merge results with
hash-based deduplication, then apply time filters.

**Before:** O(N × P × J) where N=all packets, P=pubkeys, J=avg JSON
length
**After:** O(M × P) where M=packets per pubkey (typically small), plus
O(R log R) sort for pagination correctness

Results are sorted by `FirstSeen` after merging to maintain the
oldest-first ordering expected by the pagination logic.
