Incorrect Handling of Media Filenames

### Checked for duplicates?

- [X] This issue is not a duplicate

### Does it also happen in the desktop version?

- [X] This bug does not occur in the latest version of Anki

### What are the steps to reproduce this bug?

1. Create a long screenshot in Brave for Android (from sharing hub)
2. The resulting file has a filename template that follows this example: chrome_screenshot_May 22, 2024 4_54_13 PM GMT+03_00
3. Add above file to a card
4. Use the media check tool > Image file is deemed unused

### Expected behaviour

The file shouldn't show up in the media check as unused. The check result should be empty (no unreferenced cards).

### Actual behaviour

The file is detected as unreferenced, and isn't included in exports.

### (Optional) Anything else you want to share?

I tried changing the filename to 'chrome' and it worked properly, tried removing spaces and some other characters but it didn't help.

Here's a sample deck (single card) and the media file seperately:
