feat: New BookingComponent

[Dunkstormen]

This solves #25, #21 and #17 and partially #31 as some unused packages were removed.

• Rewritten the BookingComponent for better readability.
• Introduced a BookingHelper instead of modules being spread across multiple tsx files in utils folder.
• Cleaned out unused packages.
• Introduced use of the new Positions API endpoint provided by CC.
• Removed Snowfall due to dependency issues making the build process fail. (Put forward a PR on the react-snowfall repo, maybe it will be back soon?)

Thanks for the contribution. I haven't looked at prior PRs, I'll ask a dumb question that I hope you'll excuse me for.

What about moving the snowfall removal outside of this PR? Given it was added for Christmas, it seems a bit early. Alternatively, revert the React 19 upgrade if it wasn't due to a hard requirement.

I've applied the suggested changes aswell as downgrading to react-18 for now. I'll keep you posted on if my PR for react-19 support gets merged.
