[Bug]: JPEG-XL with 16-bit float breaks basic functionality

[Ambossmann]

Checklist

• I am using an up-to-date version.
• I have read the documentation.
• I have searched existing issues.

TagStudio Version

Alpha 9.5.1

Operating System & Version

NixOS unstable; Windows 10

Description

When a JPEG-XL image that uses 16-bit float is in a TagStudio library, then the tile for the file doesn't show thumbnail, file type or file name.

Additionally, the sidebar doesn't update when selecting the file, instead keeping its previous state.

This is likely caused by pillow-jxl-plugin not supporting 16-bit float at this point in time and throwing an error instead.

Expected Behavior

The missing thumbnail is expected. However, TagStudio should catch the error and proceed normally like with any other file for which no thumbnail could be generated. This means it should still show file name and type and the sidebar should also work as usual.

Steps to Reproduce

1. Add a JPEG-XL image using 16-bit float into a library
2. Observe broken state

Here is a test image that triggers the issue. GitHub does not allow uploading .jxl files, so I gzipped it. Test2.jxl.gz
