[Feature Request] Add ability to change PATHS inside the settings within the UI

Instead of having to add path for SD models, loras etc in the Bat file arguments, make it an option in the settings when the seb server is open.

SD dot NEXT did something similar, you can copy their code or whatever.

Thanks

No files or tests are named. Start by tracing how BAT-file path arguments are parsed and how the UI settings are defined; identify the paths that must be editable, including SD models and loras. Done means those paths can be configured in the open server's settings and are used when the server runs.
