/**
 * E2E-style tests for AuthController signup, login, and token-grant flows.
 *
 * Drives the controller's extracted route-handler methods directly with
 * synthetic req/res shapes — that way we exercise the full controller
 * logic (DB writes via in-memory sqlite, real password hashing, real
 * JWT signing/verifying via TokenService, real PermissionService writes)
 * without needing the HTTP layer's middleware (rate limiting, captcha,
 * anti-CSRF) to play along. Aligns with AGENTS.md: "Prefer test server
 * over mocking deps."
