Implements the change-password endpoint: - Per-IP rate limit reusing services/rate_limit - Required fields, mismatched-confirm, policy, wrong-current branches each redirect with a specific ?error= key - Rotates digest + password_changed_at, then re-stamps the current session marker so this browser stays logged in while other sessions get rejected by load_current_user Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
