* Caddy Import Debug Tests - POC Implementation
*
* Purpose: Diagnostic tests to expose failure modes in Caddy import functionality
* Specification: docs/plans/caddy_import_debug_spec.md
*
* CRITICAL FIXES APPLIED:
* 1. ✅ No loginUser() - uses stored auth state from auth.setup.ts
* 2. ✅ waitForResponse() registered BEFORE click() to prevent race conditions
* 3. ✅ Programmatic Docker log capture in afterEach() hook
* 4. ✅ Health check in beforeAll() validates container state
*
* Current Status: POC - Test 1 only (Baseline validation)
