fix: allow invite codes for users with verified mails (#9962)

# Which Problems Are Solved

Users who started the invitation code verification, but haven't set up
any authentication method, need to be able to do so. This might require
a new invitation code, which was currently not possible since creation
was prevented for users with verified emails.

# How the Problems Are Solved

- Allow creation of invitation emails for users with verified emails.
- Merged the creation and resend into a single method, defaulting the
urlTemplate, applicatioName and authRequestID from the previous code (if
one exists). On the user service API, the `ResendInviteCode` endpoint
has been deprecated in favor of the `CreateInviteCode`

# Additional Changes

None

# Additional Context

- Noticed while investigating something internally.
- requires backport to 2.x and 3.x
