**PIC UI always accessible (service_access=[])**
Remove the per-peer Caddy:80 ACCEPT/DROP rule from apply_peer_rules.
Service access was enforced at two layers (iptables DROP + CoreDNS ACL),
but the iptables layer also blocked the PIC web UI served through Caddy.
CoreDNS ACL alone is sufficient — DNS blocks service hostnames; the UI
path through Caddy remains reachable regardless of service_access value.
**Exit-relay internet routing (route_via another cell)**
update_peer_ip validated new_ip as a single ip_network, rejecting the
comma-separated '10.0.1.0/24, 0.0.0.0/0' string passed by
update_cell_peer_allowed_ips(add_default_route=True). The AllowedIPs
in wg0.conf was never updated, so WireGuard never routed internet traffic
through the exit cell's tunnel. Fix: validate each CIDR individually and
apply the change live via wg set without a container restart.

- _build_acl_block: put all blocked IPs for a service in ONE acl block instead
of one block per peer — the first block's allow-all was silently granting
access to every peer after the first blocked one (first-match semantics)
- generate_corefile: add 'reload' plugin so SIGUSR1 triggers Corefile reload
in newer CoreDNS builds (without it the signal was a no-op)
- tests/test_firewall_manager.py: new tests for single merged ACL block and
the reload directive
- tests/e2e/api/test_peer_access_update.py: e2e tests for service_access,
internet_access, and peer_access updates persisting live to iptables/CoreDNS
- tests/e2e/api/test_cell_to_cell.py: e2e tests for cell-to-cell connection
management, permissions API, and cross-cell service access restrictions
