dmolinari b619c05762 feat(audit): security events en Auth + authorization handlers (UDT-010 B9) ...

Instruments auth pipeline with ISecurityEventLogger per #REQ-AUTH-SEC:

LoginCommandHandler:
- login success → action=login result=success actorUserId=user.Id
- login failure disaggregated internally (client still sees 401 unified):
  user_not_found / user_inactive / invalid_password
  — attempts captured with attemptedUsername + FailureReason

LogoutCommandHandler:
- action=logout result=success actorUserId=cmd.UsuarioId

RefreshCommandHandler:
- refresh.issue success on successful rotation
- refresh.reuse_detected failure when revoked token is presented (chain
  revoke already happens; we add the security event with metadata.familyId)
- refresh.issue failure for: token_expired / sub_mismatch / user_not_found /
  user_inactive

PermissionAuthorizationHandler:
- permission.denied failure on require-permission rejection, with metadata
  { permissionRequired, endpoint, method }. ActorUserId from JWT sub.

DI: ISecurityEventLogger was already registered by B6 (AddInfrastructure).

Test updates: 4 test classes now inject ISecurityEventLogger mock:
- LoginCommandHandlerTests, LogoutCommandHandlerTests, RefreshCommandHandlerTests
- PermissionAuthorizationHandlerTests (Api.Tests)

Suite: 378/378 Application.Tests + 141/141 Api.Tests = 519/519 passing.
