fix: SUG-6 API key modal, SUG-4 project activity filter, WooCommerce health auth

- SUG-6: Replace auto-closing inline banner with persistent modal on Connect
  page — key stays visible until user clicks "Done"
- SUG-4: Filter health_metric_recorded/health_check from project detail activity
- WooCommerce: Accept consumer_key/consumer_secret credentials (preferred) with
  username/app_password fallback; fix health check to use WC endpoint and creds
