fix: use TotalSeconds/TotalMilliseconds in WaitAndRetry timeout comparison

TimeSpan.Seconds returns only the seconds component (0-59), not the
total seconds. For timeouts >= 60 seconds (e.g. the default 60s),
.Seconds is 0 because it's exactly 1 minute. This caused WaitAndRetry
to always throw a timeout exception instead of retrying, with the
misleading message 'The request took longer than the 0 milliseconds
allowed'.

The fix uses .TotalSeconds and .TotalMilliseconds which return the
full value regardless of magnitude.

Added regression tests for timeouts >= 60s and correct millisecond
reporting in error messages.

Bumps version to 3.2.1.

+- Fixed `WaitAndRetry` using `TimeSpan.Seconds` and `TimeSpan.Milliseconds` (component-only, 0-59 / 0-999) instead of `TimeSpan.TotalSeconds` and `TimeSpan.TotalMilliseconds`. This caused retries to always fail with a spurious timeout exception for any timeout >= 60 seconds (including the default), with the misleading message "The request took longer than the 0 milliseconds allowed".
