Drift-audit Group 8 (lifecycle gaps): - change_password no longer 500s for OAuth-only users: short-circuit when password_hash is None (verify_password would crash on None) so the route returns a clean 4xx instead of a 500. - register_with_invitation no longer locks the invitee out on a username collision: create the user FIRST, then mark the token used, so a failed creation (409) leaves the single-use invite valid for retry. - update_event re-arms reminder_sent_at when start_dt/reminder_minutes change, so a rescheduled event fires again instead of being permanently suppressed. - Migration 0061: uq_topic_per_rulebook / uq_rule_per_topic become PARTIAL unique indexes (WHERE deleted_at IS NULL). Trashing 'X' then recreating it no longer 500s on the dead row's title. Model __table_args__ updated to match. Deferred: per-occurrence reminders for recurring events (event_scheduler) — needs a per-occurrence reminder-state design, not a one-line gate tweak.
