[Bug]: Error "'NoneType' object has no attribute 'split'" on attribute 'publishedAt'

[DL-Vadric]

Describe the bug.

When trying to select a model that is missing a value in the 'publishedAt' attribute, the GUI shows "Error" in every field and prevents interacting with the model itself. There is no crashing or freezing and you can select a different model. You simply cannot interact with the one lacking that value. The error message in the console shows it is hitting the problem at line 650 in civitai_api.py. The full log is provided in the appropriate field below here.

Steps to reproduce the problem.

1. Attempt to select any model in the CivitAI+ Browser that has no value for 'publishedAt' provided.
2. Every field in the GUI will show "Error" and you cannot use any options for the model

Expected behavior

Every available field in the CivitAI+ browser GUI will display, any unavailable fields are left blank or have a default value provided, and the selected model can be updated/downloaded.
