fix: harden unset price models tab batch copy, feedback, and memo equality

Persist committed editor drafts to the source model during batch copy so
targets never carry pricing the source would lose, surface loading/error
states for the enabled-models query, and compare saved* props in the
visual editor memo so rows leave the unset list reliably after save.
