The task

Several Vuelidate 2 validators used for cross‑field validation (`requiredIf`, `requiredUnless`, `not`, `or`, `and`) do not correctly preserve the `this` context of the Vue component, and do not properly handle async conditions or wrapped validators. This breaks common patterns that worked in Vuelidate 1.
