Three fixes:
1. Extend the docker-exec safety guard in wireguard_manager to also check
for 'wg_confs' in the config path. When running unit tests on the host
the API uses /app/config/wireguard/wg0.conf (no wg_confs subdir), so the
old '/tmp/' | 'pytest' check didn't fire — _syncconf and friends were
executing live 'docker exec cell-wireguard wg set' calls against the
running container, removing real VPN peers that didn't appear in the
test config. The wg_confs subdir only exists inside the container mount,
so its presence reliably gates live calls.
2. Fix get_split_tunnel_ips() wrong path: self.data_dir + 'api/cell_links.json'
→ self.data_dir + 'cell_links.json'. The extra 'api/' segment produced
/app/data/api/cell_links.json inside the container instead of the real
/app/data/cell_links.json, so connected cells were silently excluded from
split-tunnel CIDRs.
3. update_peer_ip_registry and ip_update now also call
wireguard_manager.update_peer_ip so wg0.conf AllowedIPs stay in sync when
a peer's VPN IP changes at runtime (previously only peers.json was updated).
