improvement(kb): workspace permissions system reused here (#761)

* improvement(kb-perms): use workspace perms system for kbs

* readd test file

* fixed test

* address greptile comments

* fix button disabling logic

* update filter condition for legacy kbs

* fix kb selector to respect the workspace scoping

* remove testing code

* make workspace selection and prevent cascade deletion

* make workspace selector pass lint

* lint fixed

* fix type error
