/**
 * Block E5 — Merge queue smoke tests.
 *
 * Integration paths (enqueue → process-next → merge) need a seeded test DB
 * + a real bare repo on disk. Here we cover:
 *  - helper shape (types + default values)
 *  - route-level auth guards (302 redirects to /login for write actions)
 *  - 404 for missing repo on read path
