Reduce session expiry from 30 days to 7 days of inactivity while preserving a 30-day absolute token lifetime for itsdangerous: - SESSION_MAX_AGE_DAYS=7: sliding window for DB expires_at + cookie - SESSION_TOKEN_HARD_CEILING_DAYS=30: itsdangerous max_age (prevents rejecting renewed tokens whose creation timestamp exceeds 7 days) - get_current_user: silently extends expires_at and re-issues cookie when >1 day has elapsed since last renewal - Active users never notice; 7 days of inactivity forces re-login; 30-day absolute ceiling forces re-login regardless of activity Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
