Fix card list UI layout shifts (jumps) on load

This commit fixes layout shifts that occur on card list part of the page
when the page is initially loaded.

- Resolve issue where card list starts with minimal width, leading
  to jumps in UI until correct width is calculated on medium and
  big screens.
- Dispose of existing `ResizeObserver` properly before creating a new
  one. This prevents leaks and incorrect width calculations if
  `containerElement` changes.
- Throttle resize events to minimize width/height calculation changes,
  enhancing performance and reducing the chances for layout shifts.

Supporting CI/CD improvements:

- Enable artifact upload in CI/CD even if E2E tests fail.
- Distinguish uploaded artifacts by operating system for clarity.
