fix: twilio code generation and verification (#8728)

# Which Problems Are Solved

The recently added possibility to generate and verify codes through
Twilio verification service did failed on checking OTP SMS code through
the session API. Additionally, password codes generated by the V2 API
and sent through phone would always use the internal generator and
verification mechanism rather than the configured.

# How the Problems Are Solved

- Correctly set the verifier for OTP SMS for the session API
  - Always use the internal verifier for OTP Email (for now)
- Select the generator / verifier based on the configuration for
password codes with notification type SMS for V2 APIs

# Additional Changes

None

# Additional Context

- relates to #8678
- reported by customer
