fix: resolve file deletion navigation issue and improve delete modal

[HarshMN2345]

What does this PR do?

This PR fixes a critical bug in the storage bucket file deletion functionality where clicking the "Delete" option in the file action menu would navigate to the file preview page instead of opening the delete confirmation modal, preventing users from deleting files.

Key Changes:

1. Fixed event handling to prevent unintended navigation when clicking delete button
2. Added event.stopPropagation() and event.preventDefault() to action menu handlers
3. Improved the delete confirmation modal with better file information display
4. Enhanced UI with file metadata (type, size) and clearer warning messages about permanent deletion

Test Plan

1. Log into the Appwrite Console and open any project
2. Navigate to Storage → Buckets → choose any bucket
3. Upload a test file
4. In the file list, click the "•••" menu next to your file
5. Click "Delete"
