Depends on D19905. Ref T13222. In D19843, I refactored this stuff but $jump_into_hisec was dropped.

This is a hint to keep the upgraded session in hisec mode, which we need to do a password reset when using a recovery link. Without it, we double prompt you for MFA: first to upgrade to a full session, then to change your password.

Pass this into the engine properly to avoid the double-prompt.

• Used bin/auth recover to get a partial session with MFA enabled and a password provider.
• Before: double MFA prompt.
• After: session stays upgraded when it becomes full, no second prompt.
