🐛 Fix schema validation for references from other sets

When creating a token with a name that conflicts with existing
hierarchical token names (e.g., 'accent-color' when 'accent-color.blue.dark'
exists), the validation throws an error via rx/throw. However, the
rx/subs! subscriber in generic_form.cljs had no error handler, causing
an unhandled exception that resulted in an 'Internal Error' crash.

This fix adds an error handler that:
1. Catches validation errors from the reactive stream
2. Uses humanize-errors to convert them to user-friendly messages
3. Displays the error in the form's extra-errors field

Before: Crash with 'Internal Error' dialog
After: Form shows validation error message

Fixes #8110
