Kpa-clawbot 088b4381c3 Fix: Hash Stats 'By Repeaters' includes non-repeater nodes (#654) ...

## Summary

The "By Repeaters" section on the Hash Stats analytics page was counting
**all** node types (companions, room servers, sensors, etc.) instead of
only repeaters. This made the "By Repeaters" distribution identical to
"Multi-Byte Hash Adopters", defeating the purpose of the breakdown.

Fixes #652

## Root Cause

`computeAnalyticsHashSizes()` in `cmd/server/store.go` built its
`byNode` map from advert packet data without cross-referencing node
roles from the node store. Both `distributionByRepeaters` and
`multiByteNodes` consumed this unfiltered map.

## Changes

### `cmd/server/store.go`
- Build a `nodeRoleByPK` lookup map from `getCachedNodesAndPM()` at the
start of the function
- Store `role` in each `byNode` entry when processing advert packets
- **`distributionByRepeaters`**: filter to only count nodes whose role
contains "repeater"
- **`multiByteNodes`**: include `role` field in output so the frontend
can filter/group by node type

### `cmd/server/coverage_test.go`
- Add `TestHashSizesDistributionByRepeatersFiltersRole`: verifies that
companion nodes are excluded from `distributionByRepeaters` but included
in `multiByteNodes` with correct role

### `cmd/server/routes_test.go`
- Fix `TestHashAnalyticsZeroHopAdvert`: invalidate node cache after DB
insert so role lookup works
- Fix `TestAnalyticsHashSizeSameNameDifferentPubkey`: insert node
records as repeaters + invalidate cache

## Testing

All `cmd/server` tests pass (68 insertions, 3 deletions across 3 files).
