[2pt] (day-2-2) Create the home page

[Olivier-Kango]

• Home page (categories page)
  • When the user logs in, they are presented with the categories page.
  • For each category, the user can see their name, icon and the total amount of all the transactions that belongs to that category.
  • When the user clicks (or taps) on a category item, the application navigates to the transactions page for that category.
  • There is a button "add a new category" at the bottom that brings the user to the page to create a new category.
