Feat: Password Reset Email For Users

[Waptech07]

This PR contains the implementation of [POST] /api/v1/auth/password-reset-email [UNPROTECTED Endpoint]

Description

Added functionality for sending password reset emails. This includes creating a new endpoint /password-reset-email, a utility function to generate reset tokens, and integration with an email service to send the password reset email. The email contains a secure link for users to reset their passwords.

This is an implementation of an open issue #51

​## Addition
I added fastapi-mail dependency to the requirements.txt file. fastapi-mail is required for sending of emails.

Motivation and Context

This change is required to allow users to reset their passwords securely if they forget them. It enhances the security and user experience of the application.

​

How Has This Been Tested?

The new functionality has been tested using pytest, httpx, and Postman. Tests include:

• Sending a password reset email to an existing user.
• Handling a request to send a password reset email to a non-existent user.

Test environment:

• PostgreSQL database for storing user information.
• Async testing setup using FastAPI, httpx, and pytest.
