fix: disable Redis TLS for test webapp — all connections were timing out on TLS handshake

The webapp's cacheStore and rateLimiter Redis connections default TLS to
enabled. Every request with a valid auth header used these connections,
causing connect ETIMEDOUT (TLS handshake against a non-TLS Redis server).
REDIS_TLS_DISABLED=true cascades to all 15+ *_REDIS_TLS_DISABLED env vars.
