[FEATURE]: Implement Forgot Password Flow

[amaan1114]

Feature Summary

Implement a complete "Forgot Password" flow that allows users to securely reset their password if they are unable to access their account.

---

Problem Statement

AsyncNode currently does not provide a password recovery mechanism for users who forget their password.

Without this feature:

• Users cannot regain access to their accounts without administrator intervention.
• The authentication experience is incomplete.
• User experience and accessibility are negatively impacted.

A secure password reset flow is an essential feature for any production-ready authentication system.

Proposed Solution

Implement a complete password recovery workflow consisting of the following steps:

1. Add a Forgot Password option on the sign-in page.
2. Allow users to request a password reset by entering their registered email address.
3. Generate a secure, time-limited reset token (or OTP).
4. Send the reset link or verification code via email.
5. Verify the token before allowing the user to reset their password.
6. Allow users to create a new password.
7. Invalidate the reset token after successful password reset or expiration.
8. Return appropriate success and error responses for all possible scenarios.

The implementation should follow the existing authentication architecture and security best practices.

Benefits

• Completes the authentication system.
• Improves user experience and account recovery.
• Reduces administrative overhead.
• Aligns AsyncNode with modern authentication standards.
• Enhances the platform's production readiness.

Additional Context

• Reset tokens should be securely generated and expire after a configurable period.
• Password reset tokens should be single-use.
• Existing password hashing mechanisms should be reused.
• The implementation should include both backend APIs and frontend user interface updates.
• Error messages should avoid revealing whether an email address is registered to prevent user enumeration attacks.
