Kpa-clawbot 5fa3b56ccb fix(#662): GetRepeaterRelayInfo also looks up byPathHop by 1-byte prefix (#1086)
## Summary

Partial fix for #662.

`GetRepeaterRelayInfo` was reporting "never observed as relay hop" /
`RelayCount24h=0` for nodes that clearly DO have packets passing through
them — visible on the same node detail page in the "Paths seen through
node" view.

## Root cause

The `byPathHop` index is keyed by **both**:
- full resolved pubkey (populated when neighbor-affinity resolution
succeeds), and
- raw 1-byte hop prefix from the wire (e.g. `"a3"`)

`GetRepeaterRelayInfo` only looked up the full-pubkey key. Many ingested
non-advert packets only carry the raw 1-byte hop — so any repeater whose
path appearances are all raw-hop entries returned 0, even though the
path-listing endpoint (which prefix-matches) renders them.

Example node: an `a3…` repeater on staging has ~dozens of paths through
it in the UI but the relay-info function returns 0.

## Fix

Look up under both keys (full pubkey + 1-byte prefix) and de-dup by tx
ID before counting.

## Trade-off

The 1-byte prefix CAN over-count when multiple nodes share a first byte.
This trades a possible over-count for clearly false zeros. The richer
disambiguation done by the path-listing endpoint (resolved-path SQL
post-filter via `confirmResolvedPathContains`) is out of scope for this
partial fix — adding it here would mean disk I/O inside what is
currently a pure in-memory lookup. Worth a follow-up if over-counting
shows up in practice.

## TDD

- Red commit (`test: failing test for relay-info prefix-hop mismatch`):
adds `TestRepeaterRelayActivity_PrefixHop` that builds a non-advert
packet with `PathJSON: ["a3"]`, indexes it via `addTxToPathHopIndex`,
then asserts `RelayCount24h>=1` for the full pubkey starting with `a3…`.
Fails on the assertion (got 0), not a build error.
- Green commit (`fix: GetRepeaterRelayInfo also looks up byPathHop by
1-byte prefix`): the lookup change. All five
`TestRepeaterRelayActivity_*` tests pass.

## Scope

This is a **partial** fix — addresses the read-side prefix mismatch
only. Issue #662 is a 4-axis epic (also covers ingest indexing
consistency, UI surfacing, and schema). Leaving #662 open.
