Add email sending functionality to app.py

Implemented a new send_email function to allow users to send job application emails with CV attachments directly from the application. Enhanced the UI to include input fields for sender and receiver email addresses, subject, and an editable email body. This update improves user experience by streamlining the email generation and sending process, making it more efficient and user-friendly.
