fix(auth): implement proper debounce ref for forgot password requests

[javidan-io]

What does this PR do?

This PR fixes a bug in the ForgotPassword component where the debounced submit function was being recreated on every React render. By moving the lodash.debounce wrapper into a useRef, we ensure the debounce timer properly persists across renders.

Additionally, it removes an unnecessary async/await from handleSubmit since lodash.debounce does not return a Promise, preventing misleading execution flows.

Visual Demo (For contributors especially)

N/A - This is a logic/performance fix with no visual changes to the UI.

Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected).
• I have updated the developer docs in /docs if this PR makes changes that would require a documentation change. If N/A, write N/A here and check the checkbox. (N/A)
• I confirm automated tests are in place that prove my fix is effective or that my feature works.

How should this be tested?

1. Open apps/web/modules/auth/forgot-password/forgot-password-view.tsx locally and temporarily comment out the if (loading) { return; } check inside handleSubmit.
2. Run the application locally and navigate to /auth/forgot-password.
3. Open your browser's Developer Tools and go to the Network tab.
4. Enter an email address.
5. Rapidly double-click (or spam) the "Request password reset" button.
6. Verify in the Network tab that only one request is made to /api/auth/forgot-password, confirming the debounce is working correctly.
7. (Don't forget to uncomment the loading check afterwards!)
