📔 Objective

Uses new SDK method PureCrypto.decrypt_user_key_with_master_key being introduced in bitwarden/sdk-internal#465, to decrypt UserKey with MasterKey.

This is to isolate type 0 decryption to just go through an isolated SDK code path.
Note currently key connector and master password login go through this code path and should be the focus.
