Add maintenance page served by nginx during deploys

Browse Source 
When the SvelteKit upstream is unreachable (container restart, deploy)
nginx now serves a static, brand-styled "Be right back" page instead
of the default 502/503. Auto-reloads after 60s so visitors don't sit
on it once the app is back.

- nginx/maintenance.html: self-contained, no external assets, inline
  paw SVG, brand colours, contact details fallback
- nginx/nginx.conf: proxy_intercept_errors + error_page 502/503/504
  on both location blocks; 2s proxy_connect_timeout so nginx fails
  over fast instead of holding the connection for 60s

Deploy note: the html file needs to live at /var/www/html/maintenance.html
inside the nginx container (already mounted from /docker/wordpress/goodwalk.co.nz/html).
