[PM-5302] Refactor Passkey feature enable/disable logic (#7242) 

* feat: add missing tests for `isFido2FeatureEnabled`

* feat: add user logged in check

* chore: rewrite with cartesian product

* chore: remove test

The test was more complex than the actual function, removing.

* feat: add domain exclusion

* feat: add origin equal vault case

* chore: clean up the old code from `content-secript`

* feat: return early to avoid making api calls

* fix: prettier linting

* fix: incorrect logic inversion
