Extend SDK to include FrontendAPI calls

[incorbador]

Why

We have a Firebase extension that spins up a number of Firebase functions that run NodeJS. In them so far we directly make use of generated clients for frontendAPI and backendAPI. As we now have the new node-sdk we should use it inside this firebase extension. To make this possible we need to add the following calls:

• passKeyRegisterStart
• passKeyRegisterFinish
• webAuthnRegisterStart
• webAuthnRegisterFinish
• passKeyMediationStart
• passKeyLoginStart
• passKeyLoginFinish
• emailCodeLoginStart
• emailCodeConfirm
• userDelete
• userGet
• webAuthnCredentialList
• webAuthnCredentialDelete
• userUpdate

Firebase extension code: corbado_auth_firebase (the important file is corbado_service.ts)

Acceptance criteria

• [ ] all the generated code inside the firebase extension can be replaced by the node-sdk

Implementation idea

• add the required methods
• write integration tests (I would skip the ones for webAuthnRegisterFinish, passKeyRegisterFinish and passKeyLoginFinish because testing them is hard as you need to mock the authenticator)
• replace the generated code in the Firebase extension with the node-sdk
