bug:Peers stats count looks inconsistent (/admin/v1/peers/stats)

[AYAHASSAN287]

Summary

When more than one relay peer is connected, GET /admin/v1/peers/stats reports an incorrect total under Relay peers. Specifically, "Total relay peers" is 1 while other sections (and GET /admin/v1/peers) indicate 2+ relay peers are connected.

Reproduction

Run test test_admin_peers_stats_counts and compare these values:

• Relay peers["Total relay peers"]
• By Protocols["/vac/waku/relay/2.0.0"]
• The number of connected peers from GET /admin/v1/peers

Expected behavior

Relay peers["Total relay peers"] should equal the actual number of connected relay peers (e.g., 2 when two are connected). All counts within GET /admin/v1/peers/stats should be internally consistent and also match GET /admin/v1/peers.

Actual behavior

With two relay peers connected, the stats endpoint returns something like:

{
  "Relay peers": {
    "Total relay peers": 1
  },
  "By Protocols": {
    "/vac/waku/relay/2.0.0": 2
  }
}

Meanwhile, GET /admin/v1/peers (and the actual connections) show 2 relay peers.
