Add styled profile.html page with user details

[Lakshmihollat]

This update introduces a new profile.html template that matches the overall Peer Prep UI theme for a cohesive user experience.
The page dynamically displays user-specific details such as the username, email address, and account creation date using Django’s {{ user }} context.
It also includes quick navigation and action buttons for:
Accessing the Dashboard
Changing password via the reset link
Logging out securely using a POST form
The layout uses the existing CSS from index.css to maintain consistent color schemes, typography, and animations across all pages.
The design features responsive cards, glowing highlights, and hover effects for a modern and engaging look.
