Add missions components

[diarisdiakite]

In this PR, I:

• Added the missions' main components:
• Created basic structure for Missions - Setup #44
• Fetch missions - Fetch data #42](https://github.com/diarisdiakite/space-travelers/issues/42)
• Displayed the missions - Lists render #39](https://github.com/diarisdiakite/space-travelers/issues/39)
• A joining and a cancellation buttons have been added with logic to be completed. I will open a new PR for this fonctionality.
• I also added a user components for the profile display. Based on the logger implementation, we will decide what to do.

Note: I may still have console.log statements in the code. They will be removed before submission.
