content: add Capital sponsor to partner marquee + fix MSS livestream embeds

- Add the Capital Asset Management logo to the partner/sponsor marquee on the
  homepage and Support page (both carousel groups, EN/MK/SI).
- Fix the Meet Student Slovenia livestream embeds: the 2024 page was embedding
  the 2023 recording. Now 2024 embeds the 2024 live (00GGIfVx8wA) and 2023
  embeds the 2023 live (DJD02mQIE98), as proper iframes on all three languages
  (MK/SI 2024 previously had only a placeholder "#" link).

 <h2 id="livestream">For those not physically present with us</h2>
 <p>We know that not everyone managed to attend the NLB Gallery, but we therefore provided a high-quality livestream. The event was broadcast live and is now available for re-watching. If you want to feel the atmosphere and hear the honest stories from the panel, you can watch the entire event here 👇</p>
