[PM-21147] User key transferred over ipc within desktop app without its prototype (#15047)

* user key transferred over ipc within desktop app without its prototype.

`UserKey` object was transferred over IPC as regular `Object` type and not recreated as `SymmetricCryptoKey` type, losing its original functions and properties. As a result `inner` method did not exist and user key silently failed during decryption of encrypted client key halves during biometric unlock.

* ipc biometrics serializable user key type

* use encrypt service directly for decryption

* moving electron key service to KM

* log error when unlock via biometrics fails with exception in lock component

* bring back tech debt comment

* lock component logging prefix
