Move to SpeziValidation package

♻️ Current situation & Problem

Currently, SpeziAccount contains a lot of code that is not specific to account management. One part is input validation. StanfordSpezi/SpeziViews#21 introduces the new SpeziValidation library, based on previous code in SpeziAccount. This PR makes the efforts to move to that new software package and greatly simplify the SpeziAccount code base.

⚙️ Release Notes

• Update to SpeziValidation, a new one-stop software package for input validation

📚 Documentation

Documentation was addressed where needed.

TBA: Some documentation still requires external links once the SpeziViews PR is merged.

✅ Testing

Tests were adapted where needed. Nothing new was added.

This PR still misses some external link to the latest SpeziViews documentation once StanfordSpezi/SpeziViews#21 is merged and tagged. And of course updating the Package.swift file to the new release version.
Other than that, the PR is ready to review.

Thank you for all the changes and great to see Spezi Validation in action!

Looked over the PR and it looks great. Addressing the last PRs and pulling in the latest version of SpeziViews sounds good and I am happy to see the PR being merged 🚀
