Debian 0307dc68bb feat(fw): Models + Repos für Firewall-v2 (6 Entities)
Models (internal/models/):
* FirewallAddressObject (host|network|range|fqdn)
* FirewallAddressGroup mit MemberIDs gorm:"-"-Slice
* FirewallService (proto+ports, builtin-Flag)
* FirewallServiceGroup mit MemberIDs
* FirewallRule (v2-Shape, src/dst nullable refs, exactly-one-of-Validation
  in Handler-Layer)
* FirewallNATRule (kind=dnat|snat|masquerade, alle nullable)

Repos (internal/services/firewall/, ein Paket):
* AddressObjectsRepo, AddressGroupsRepo (mit Members-Junction-Ops)
* ServicesRepo (refused Update/Delete für builtin=TRUE Rows),
  ServiceGroupsRepo
* RulesRepo, NATRulesRepo
Jeweils Standard-CRUD; Group-Repos handhaben Members atomic in einer
TX (Update ersetzt komplette Membership).

Handler + Renderer-Rewrite + Frontend folgen in den nächsten
Commits.
