ci: fixed faulty carousel and table tests

[agliga]

• Added mocking timeouts for carousel. Carousels had some flaky tests which would fail due to timeout issues. This should fix that
• Added a mock for scrolltransition. This was what was causing a lot of flakiness and slow tests.
• Tables had some faulty tests which were not actually waiting for assetions. We had a await waitFor in a forEach. Changed this to do a map and await for Promises.all
• Updated tables to actually correctly disable links (links should not be "disabled")

Bonus changes

• Updated react to clean up fake timers
• Added a mock to debounce. This debounce seems to have been triggering after the test is shut down.

Pull request overview

Stabilizes flaky carousel and table loading tests by improving async handling and mocking time/tween behavior, plus updates table loading markup expectations around disabling interactive elements.

Changes:

• Reworked table loading tests to properly await assertions (replacing forEach(async ...)).
• Added Vitest fake timers + mocked scroll transition to reduce carousel test flakiness/timeouts.
• Updated table header sort button markup to apply tabindex="-1" while loading (and snapshot updates).
