fix(login): send invite codes only for users with unverified email (#10943)

# Which Problems Are Solved

When a user with no authentication methods attempted to log in, the
system always set `invite=true` in the verification flow, regardless of
whether their email was already verified. This could cause errors when
trying to send invite codes to already initialized users.

# How the Problems Are Solved

Added conditional logic to determine whether to send an invite code
based on the user's email verification status:

This prevents errors when attempting to send invite codes to users who
have already verified their email and been initialized, while still
properly handling new users who need invitation flows.
