Fix flaky page test

[falkoschindler]

Motivation

The test test_warning_if_response_takes_too_long is flaky in CI. When the page's response_timeout fires and the client is deleted, the resulting incomplete page response causes Selenium's get() to hang until its internal script timeout (~30s), throwing a TimeoutException before the test's log assertion is ever reached. This has been observed failing on Python 3.10 and 3.14 in CI (example run).

Implementation

Replace screen.open('/') with a plain httpx.get() request. The test only verifies that a server-side warning is logged — it doesn't need a fully loaded browser page. Using httpx avoids Selenium entirely, eliminating the script timeout issue while keeping the same assertion.

Progress

• I chose a meaningful title that completes the sentence: "If applied, this PR will..."
• The implementation is complete.
• This is not a security issue.
• Pytests have been updated.
• Documentation is not necessary.

Let's see if the pipeline agrees with this solution...

Mergeable as-is, but prefer robustified timings.

The commit doesnt show up -> use this instead

It should be 1.0 but 1 also works. Anyways I'm eager to close this ASAP (in family dinner btw)
