feat: Networks-Members für bridge/bond + System-Rules-Card + Theme-Revert

* Migration 0011: members JSONB für network_interfaces. Bridge/bond
  brauchen ≥1 Member (NOT VALID-Constraint, schont bestehende Rows).
  vlan/wireguard/ethernet ignorieren das Feld.
* Backend-Validation pro Typ: vlan→parent+vlan_id, bridge/bond→members,
  ethernet/wireguard→keins. Repo serialisiert via JSONB.
* Form Networks: Members-Multi-Select für bridge/bond, Composition-
  Spalte zeigt vlan-tag bzw. Member-Liste.
* Firewall-Rules-Tab zeigt jetzt SystemRulesCard ganz oben — Anti-
  Lockout (SSH/443), stateful baseline, default-deny-Erklärung.
* Theme-Tokens 1:1 mail-gateway: fontSize 13, controlHeight 34
  (vorher zu dichtes 12/28). Density kommt vom DataTable size="small".
* Makefile publish-amd64 lädt jetzt auch edgeguard-ui_*_all.deb und
  edgeguard_*_all.deb hoch (vorher nur api).
* Version 1.0.0 → 1.0.3.
