/**
 * DC-131/133 additions to the deploys routes tests: install-from-any-host.
 *
 * Covers the judge round-1 blocking issues:
 *  - POST /install accepts any https host/owner/repo (not just github.com)
 *    and forwards the optional per-request token to the bridge.
 *  - POST /gitea-repos carries {gitea_url, token} in the JSON body.
 *  - Token validation rejects non-string / oversized tokens before the
 *    proxy call.
