feat: duplicate doc moved from frontend to backend concern (#5342)

BREAKING CHANGE: collection.admin.hooks.beforeDuplicate removed and instead should be handled using field beforeDuplicate hooks which take the full field hook arguments.

* feat: duplicate doc moved from frontend to backend concern

* feat: default beforeDuplicate hook functions on unique fields

* docs: beforeDuplicate field hook

* test: duplicate doc local api

* chore: fix build errors

* chore: add access.create call to duplicate operation

* chore: perfectionist reorder imports
