Add attributes to UI filters list (#23250)

* preserve user-set min_score on attribute filters instead of bumping any 0.5 value

use model_fields_set to distinguish "user explicitly set min_score" from "Pydantic applied the generic FilterConfig default of 0.5"

* add config test for attributes

* fix attributes frontend type

* add expanded hidden field context

* extend schema modification

* special case for attributes

* i18n for attributes

* handle dedicated lpr mode

* strip unrendered FilterConfig fields from attribute filter form data to fix validation errors
