fix: prevent pseudo-element from blocking file operation clicks (#4005)

[Samm-05]

🐛 Issue

Fixes #4005

🔍 Problem

File operation dropdown actions (Rename, Delete, Create, Upload) appear but may not respond to clicks.

🧠 Root Cause

The ::before pseudo-element on .sidebar__file-item-name spans the full file row and may intercept pointer events, preventing interaction with dropdown menu items.

🛠 Solution

Added pointer-events: none to the pseudo-element so it does not block interactions.

✅ Impact

• Allows file operation actions to receive click events
• No changes to layout or structure
• Minimal and safe fix

🧪 Testing

• Verified CSS logic and behavior
• Requesting maintainers to validate interaction in their environment

📌 Notes

This is a targeted fix with minimal changes, preserving existing UI behavior.
