test: add E2E coverage for peer dashboard/services, DNS records, and WG domain access

- test_peer_dashboard_services.py (63 tests): unit tests for all API fixes
  * peer_dashboard field names (name/transfer_rx/transfer_tx vs old stale names)
  * peer_dashboard service_urls dict with correct domain-keyed URLs
  * peer_services email structure (nested smtp/imap, address not username)
  * peer_services files key (not webdav), caldav URL (calendar.dev not radicale.dev:5232)
  * peer_services wireguard DNS (not 10.0.0.1), config text with DNS line
  * DNS zone records (api/webui → Caddy, VIPs for calendar/files/mail/webdav)
  * Caddyfile generation (all service blocks including webui.dev)
  * Access control (401 anon, 403 admin on peer-only routes, 404 missing peer)
- e2e/api/test_peer_endpoints.py: fix stale field assertions, add structure checks
- e2e/wg/test_wg_domain_access.py: E2E WG tests for DNS resolution via VPN tunnel
  * All *.dev domains resolve to correct IPs via CoreDNS
  * api.dev/webui.dev must resolve to Caddy, not container direct IPs
  * CoreDNS reachability through VPN tunnel
  * Peer config DNS field correctness

 Scenarios:

-  13. Peer's My Services page loads and shows the WireGuard VPN section
