feat(audit): wire AddAuditEmission in 7 services (AUDIT-002 wave A)

Sprint SPRINT_20260408_004_Timeline_unified_audit_sink AUDIT-002.

Wire the unified audit emitter in 7 webservices that were listed in the
AUDIT-002 priority table but missing the call:
- Concelier.WebService (priority 6a)
- Excititor.WebService (priority 6b)
- SbomService (priority 8)
- Graph.Api (priority 12)
- BinaryIndex.WebService (priority 14)
- Policy.Gateway (priority 3b)
- Notifier.WebService (priority 4b)

Each adds:
- ProjectReference to __Libraries/StellaOps.Audit.Emission
- using StellaOps.Audit.Emission;
- builder.Services.AddAuditEmission(builder.Configuration) in Program.cs
  placed after auth wiring, before authorization policies.

AUDIT-002 completion criterion "AddAuditEmission() called in all 14+
service Program.cs files" is now met for the listed priority services.
Endpoint-level AuditActionAttribute decoration is a separate wave.

All 7 projects build clean against the existing Audit.Emission lib.
