feat: invite user link (#8578)

# Which Problems Are Solved

As an administrator I want to be able to invite users to my application
with the API V2, some user data I will already prefil, the user should
add the authentication method themself (password, passkey, sso).

# How the Problems Are Solved

- A user can now be created with a email explicitly set to false.
- If a user has no verified email and no authentication method, an
`InviteCode` can be created through the User V2 API.
  - the code can be returned or sent through email
- additionally `URLTemplate` and an `ApplicatioName` can provided for
the email
- The code can be resent and verified through the User V2 API
- The V1 login allows users to verify and resend the code and set a
password (analog user initialization)
- The message text for the user invitation can be customized

# Additional Changes

- `verifyUserPasskeyCode` directly uses `crypto.VerifyCode` (instead of
`verifyEncryptedCode`)
- `verifyEncryptedCode` is removed (unnecessarily queried for the code
generator)

# Additional Context

- closes #8310
- TODO: login V2 will have to implement invite flow:
