[Issue]: Calendar UI for users to enter weekly availability

[RenaudBernier]

Branch name

feature/12-calendar-frontend-component

Description

Build the calendar UI component for user scheduling:

• Users can select their weekly availabilities on a calendar that includes the next 2 weeks
• Use the same json format as the one in the db to save the availabilities locally in React
• This issue is only the calendar component frontend UI. You do not need to make APIs.
• Use the Figma design as reference

Acceptance Tests

[ ] Highlighted availabilities stay highlighted until the user refreshes the page
[ ] UI component is consistent with the Figma design
