chore(secrets): bump to Secrets 0.2.3 - visible delete modal (scadaproj#2)

0.2.3's Secrets.Ui ships ConfirmDeleteModal's own styles under
collision-proof zb-secrets-* class names. This host links no Bootstrap so
it never exhibited the invisible-modal defect, but it takes the fixed
line for parity; also rides over 0.2.1/0.2.2 (Akka-replicator fixes -
inert here, no replicator in use). Tests: 780 pass, 45 fail on macOS both
before and after the bump (NamedPipeServerStream multi-instance is
Windows-only - the fake-worker pipe harness cannot run on this platform);
zero delta from the bump.
