Fix inconsistent wildcard behavior in outbound network policy rules

[Copilot]

application: '*' in outbound access policy rules was silently skipped, while the same wildcard in inbound rules correctly produced an empty podSelector (match all). This meant the two configs below had different runtime behavior despite appearing equivalent in the NAIS console.

Changes

• networkpolicy.go: Remove the outbound.Application == "*" skip condition in egressRulesFromAccessPolicy. Apply the same wildcard handling as inbound: * → empty LabelSelector for both application and namespace fields.
• accesspolicy_max.yaml: Update existing test (which already had application: '*', namespace: t2 in outbound) to assert the expected wildcard egress rule is now generated.
• accesspolicy_egress_allow_all.yaml: New golden file test covering application: '*', namespace: '*' outbound, producing egress with empty podSelector: {} and namespaceSelector: {}.

Before / After

accessPolicy:
  outbound:
    rules:
      - application: '*'
        namespace: some-ns  # was: skipped entirely
                            # now: egress to podSelector: {}, namespaceSelector: {some-ns}
