Dashboard

Logic:

• Load the dashboard.html template.

• List users in alphabetical order with the current user at the top.

• Display the current user's full name and birthdate in the sidebar.

Frontend:

• Top: Four buttons (sidebar toggle, see bought items, help page, add new ideas).

• Center: User list in the order determined by the backend.

• Sidebar (toggleable): Access account parameters, change password and email address, add users, and log out.
