After uploading a file with a space in the name to the "Resources" section, attempting to access it results in a 404.

**To Reproduce**
Steps to reproduce the behavior:

2. Upload a file with a space in the file name
- Uploading "into_the_deep.png" works, uploading "into the deep.png" does not.

**Expected behavior**
The file loads using default browser behavior

Start by tracing the /resources/upload/ POST route and the /resources/{filename} GET route shown in the report, focusing on how the filename is handled between upload and retrieval. Reproduce the issue with “into the deep.png” and confirm that the resource loads successfully, while the existing underscore filename continues to work.
