Refactor Front-End

[lukas-rotsching]

User story

1. As a team
2. We need a clean and maintainable code base
3. So that the addition of new features is easier. Our industry partner also benefits greatly from well-structured code.

Acceptance criteria

• Go over every line of code in the front end and think about possible improvements, additional comments, potential refactorings
• Improve the code documentation and overall quality where possible
• Use Flask to build the website instead of writing long html documents yourself
• Double-check every occurrence of the words Metadata-Hub and make sure the spelling is always "Metadata-Hub", "MdH" or "MdH-OpenSearch" depending on what you need. But it has to be exactly one of those variants (case-sensitive)!
