fix: Load smart item asset path

[cyaiox]

Asset Loading Race Condition Fix

Context and Problem Statement

When dragging and dropping assets (particularly NFTs and smart items) into the canvas, there was a race condition where the asset would fail to load on the first attempt but succeed on subsequent attempts. This occurred because the asset was requested before it was fully downloaded and available in the filesystem.

Solution

Implemented a retry mechanism in the SceneContext.getFile() method to handle cases where an asset is temporarily unavailable. This provides a more robust solution without introducing unnecessary complexity.

Key changes:

• Added retry logic to getFile() with a maximum of 3 attempts
• Added 500ms delay between retries to allow for asset availability
• Improved error logging for debugging purposes

Testing

• Tested dragging and dropping NFTs - works on the first attempt
• Tested dragging and dropping Video Player - works on the first attempt
• Tested dragging and dropping smart items - works on the first attempt
• Verified retry mechanism works with console logging
• Confirmed no regressions in other asset loading scenarios

Impact

This change improves the reliability of asset loading in the Inspector, particularly for NFTs and smart items. Users will no longer experience failed first attempts when dragging and dropping these assets into the canvas.
