feat: add remediation effectiveness tracking to Problems tab

Shows whether password resets and welcome emails led to successful logins:
- Summary cards: success rate, resolved/pending/failed counts, avg time to login
- Detailed table: each action with user, type, date sent, and outcome
- Resolved = user logged in after email, Pending = <48h, Failed = no login
