Subject: [PATCH] feat: add OIDC SSO login button

Show a "Login with <provider>" button on the login page when OIDC is enabled
in the backend config, mirroring the existing SAML button.

- Login.vue: button guarded by mainConfig.oidc_enabled linking to
  /api/auth/oidc/login, with a loginOIDCButtonInfo computed label
- i18n: add login_with_oidc / login_oidc keys (English source plus the
  translated locale files)
