Integrate tailwind css and create new button library (#2098)

Introduce tailwind as new frontend styling library to replace bulma in the longer run. Also create the first new ui library `ui-buttons` which will be the new standard for buttons ins SCM-Manager. In this library we reconsidered which types of buttons should be used to create a clean and consistent ui.
