Fix: Contact Form Input Not Saving & Slow Loading Issue

[Student-aditya123]

This PR fixes two issues in the Contact Form module of the Django Portfolio project:

1. Contact page had long loading time

✨this is happens due to
❌class="php-email-form" [it is not used in django, in place of this you used class="contact-form"]
❌

Loading

❌ PHP Form JS (which blocks POST submission)
✨Because they block Django from receiving data.

2. Contact form was not saving user input

✨Issue caused by incorrect request.POST handling

✨Updated the view logic to correctly validate and save form data

✨Fixed form field mismatches in the template

Optimized the view function

🔧 Changes Made

🧪 How I Tested

2. Checked admin panel → new contact entries visible
