[Frontend] Create an input field component

[justwickedcode]

• Watch a Vue crash course to understand what it's going on with this framework. (Nuxt later, when I'll have to deal with routing and the more complicated stuff)
  • Finish the Vue Course
  • Finish the Vue Pinia State Management Course
• Implement an input field that keeps track of the typing progress.
  • Refactor the vibecoded starter template, so it does what you're wishing to.
