[fix]: StorageException during Upload & DownloadManager Failures

[namanhere23]

Bug 1: Uploading Menu Fails

When a Mess Committee member edits the menu and clicks the "Send Menu for Approval" button, the application fails to upload the generated PDF, throwing an error toast.
The error originates from the Firebase Storage SDK during the ref.putFile(uri) execution inside Firebase.kt, while the preceding Firestore checks run successfully.

Bug 2: Downloading Menu Fails ("Download Unsuccessful")

When a user clicks "Download Current Menu", a "Download Started" toast appears, but the download ultimately fails, showing a "Download Unsuccessful" notification. The system DownloadManager fails to process the Firebase Storage URL correctly.

**Possible Root Cause (Server-Side): **
Both the upload and download issues share a common root cause related to Firebase Storage configuration.

I think firebase storage is now discontinued so we need to find a new way to store files now...one probable alternative could be cloudinary.

@theayushyadav11 Due to my recent experience with cloudinary, i will suggest to use cloudflare r2 storage. Its free upto 10GB
