hzhang 92d3b4dc1b feat(frontend): OIDC login + runtime env (FABRIC_OIDC_ONLY/FIX_TO_CENTER)
- Runtime container env injected by docker/entrypoint.sh -> runtime-env.js
  (loaded before the bundle); src/lib/runtime-env.ts reads it.
  FABRIC_OIDC_ONLY hides the password form; FIX_TO_CENTER pins the
  Center base and hides its input. Dockerfile ENTRYPOINT + ENV defaults.
- LoginPage: 'Sign in with SSO' when /auth/oidc/status enabled; password
  form gated by OIDC_ONLY; center input gated by FIX_TO_CENTER.
- /oidc route (OidcCallback) redeems the fragment ticket via
  /auth/oidc/exchange and adopts the session (AuthContext.adoptSession).
