fix(tests): configurable retry delays and circuit backoff overflow

Browse Source 
Three bugs fixed:

1. Test suite timeout: add Client.RetryBaseDelayMs/RetryMaxDelayMs config
   fields (env CLIENT_RETRY_BASE_DELAY_MS/CLIENT_RETRY_MAX_DELAY_MS,
   defaults 500ms/10s). Tests override to 10ms so retry exhaustion
   completes in ms instead of ~25s per request. Suite runs in ~35s.

2. effectiveCircuitBackoff float overflow: on amd64, float64(+Inf) cast
   to int64 gives MinInt64 not MaxInt64, so the < base guard fired and
   returned base instead of the 24h sanity ceiling. Fix: check
   math.IsInf/math.IsNaN before the cast.

3. TestStartHTTPProxy_ErrorHandlerConfigured bypassed the TestSuite
   retry-delay override; now sets/restores the fields explicitly.
