Reorder Overview layout: charts hero, remove redundant health card

- System Trends promoted to full-width hero row (most important info first)
- Uptime and load average moved into Trends card header
- Removed separate System Health card (redundant with VitalsBar + Trends)
- Services + Deployments in row 2, Quick Links + WhyRating in row 3
- Taller charts (h-20), tighter gaps, cleaner visual hierarchy
