The login page now shows the service name and a "Sign in with MCIAS"
button instead of immediately redirecting to MCIAS. This lets the user
know what service they are logging into before the redirect.
- GET /login renders the landing page with SSO button
- GET /sso/redirect initiates the actual SSO redirect
- Non-SSO login form still works when SSO is not configured

Phase 11 implements the admin CLI with dual REST/gRPC transport,
global flags (--server, --grpc, --token, --ca-cert, --json), and
all commands: status, repo list/delete, policy CRUD, audit tail,
gc trigger/status/reconcile, and snapshot.
Phase 12 implements the HTMX web UI with chi router, session-based
auth (HttpOnly/Secure/SameSite=Strict cookies), CSRF protection
(HMAC-SHA256 signed double-submit), and pages for dashboard,
repositories, manifest detail, policy management, and audit log.
Security: CSRF via signed double-submit cookie, session cookies
with HttpOnly/Secure/SameSite=Strict, TLS 1.3 minimum on all
connections, form body size limits via http.MaxBytesReader.
