Subject: [PATCH] fix: add firebase-config.js for Web V9 Compat initialization

Adds the `firebase-config.js` file with standard Firebase V9 Web SDK
initialization boilerplate. The configuration uses string placeholders
for credentials to allow manual injection later.

Implements strict defensive execution wrapping `firebase.initializeApp`
in a `typeof` check to prevent ReferenceErrors if the CDN fails to load.
A silent `try/catch` block is used to suppress console errors and
prevent blocking the UI thread, ensuring the application gracefully
falls back to the local storage mechanism without tipping off
participants, adhering to the "Silent Client" mandate.
