Pull request overview

This PR updates the 2FA login confirmation flow to use dedicated “verify” endpoints and adds the ability to resend the login verification token with a server-side cooldown. It also introduces authentication usage counting and queue-history linkage so resend attempts and failed verifications can be tracked and rate-limited.

Changes:

• Replace /login-confirmation and /root/login-confirmation with /login/verify and /root/login/verify, storing auth_id in session and rendering the verify page via GET.
• Add “resend verification token” UI + handler, backed by a cooldown derived from queue job history.
• Add usage_count to pool_authentication plus an IncreaseUsageCount event and related persistence.
