When a Capybara helper times out after hitting
`Capybara.default_max_wait_time`, we will now
dump the puma server threads backtraces. This information will help us
diagnose test failures due to requests not completing within
`Capybara.default_max_wait_time`.
Example test failure output:
```
Failures:
1) User resetting password when desktop when user has multi-factor authentication configured when user has TOTP, security key and backup codes configured should allow a user to toggle from security key to TOTP and between TOTP and backup codes
Failure/Error: expect(page).to have_current_path("/u/#{user.username}/preferences/second-factor")
expected `#<Capybara::Session>.has_current_path?("/u/john/preferences/second-factor")` to be truthy, got false

### Reviewer notes
In this [flaky test
example](https://github.com/discourse/discourse/actions/runs/14087382392/job/39454911943),
the test failed because a capybara assertion did not pass within
`Capybara.default_max_wait_time`. From the screenshot below, we see that
the submit button is still loading which indicates that the request is
still being processed by the server. However, we need to know why the
server is taking more than 10 seconds to generate a response.
```
Failure/Error: expect(page).to have_current_path("/u/#{user.username}/preferences/second-factor")
expected `#<Capybara::Session>.has_current_path?("/u/john/preferences/second-factor")` to be truthy, got false
