Textfields css only and m3

[wuda-io]

Proposed changes

Improving the Style and Handling of Text Fields, since it is often difficult to re-initialize the inputs again.
With this approach, it works without using JavaScript. Also the Validation should be created dynamically.
During the rewriting, Material3 Guidlines were applied. More Info here https://m3.material.io
The HTML Structure was kept the same, so it is even backwards compatible.
There is a standard version of an input and an outlined version, see video below for appearance.
I had to remove the form tests, since the feature is now handled via CSS only.
