Kacper Sawicki 6d41bfad81 fix: improve http connection pooling for smtp notifications (#20605)
This change updates how SMTP notifications are polled during scale
tests.

Before, each of the ~2,000 pollers created its own http.Client, which
opened thousands of short-lived TCP connections.
Under heavy load, this ran out of available network ports and caused
errors like `connect: cannot assign requested address`

Now, all pollers share one HTTP connection pool. This prevents port
exhaustion and makes polling faster and more stable.
If a network error happens, the poller will now retry instead of
stopping, so tests keep running until all notifications are received.

The `SMTPRequestTimeout` is now applied per request using a context,
instead of being set on the `http.Client`.
