[Bug]: Move the sub folder settings json away from the UI's "config states" folder

[Lumerica]

Describe the bug.

The new method to create custom sub folders saves the configuration to the json file "civitai_subfolders.json" in the sub folder "config states".
The sub folder "config state" is being continuously read in the background by the UI (at least in my test case Forge UI).
Since the civitai_subfolders.json does not meet the requirement format the console generate the line expecting "created_at" to be defined in the json file.

I think the configuration file itself should stay in the extension folder rather than put its configuration in a sub-folder that is being used by default.

Ps. its a minor issue if you ask me. not causing harm imo, just that its scary to think that an extension can put its config files in a default sub folder of the root directory of the UI.

Steps to reproduce the problem.

configure some sub folder. Any startup of the UI will generate the error
[ERROR]: Config states N:\GIT\ForgeManual\config_states\civitai_subfolders.json, "created_at" does not exist

Expected behavior

have the config file stored within the extension folder itself instead.
