Add gradient banners to settings pages for visual consistency

Adds polished gradient banner headers to all configuration pages:
- System > General, Network, Updates, Backups
- Security > Authentication (updated from gray to blue/indigo gradient)
- API Access

Resource management pages (PVE, PBS, Docker, etc.) intentionally left
without banners to keep focus on node tables and operational content.
