/**
 * Tests routes /api/v1/views/* — Patch 031 JWT manager integration.
 *
 * Valide :
 *   - GET /api/v1/views/table/:slug fonctionne quand user JWT configure (mock manager)
 *   - GET /api/v1/views/table/:slug renvoie 500 clair quand creds absentes
 *     (le repo remonte BASEROW_USER_AUTH_NOT_CONFIGURED qui devient 500 via error-handler)
 *   - Slug resolution fonctionne avec le JWT manager active
