Increase font weights to medium and add prominent dashboard link

Font weight adjustments (middle ground):
- Body text: normal → 500 (medium weight)
- Table cells: normal → 500
- Form inputs: normal → 500
- Code blocks: normal → 500
- Small text: normal → 500
- Headers remain: bold
- Labels remain: bold

Result: Readable but not too light or too heavy

Dashboard link on main page:
- Added prominent black button at top
- "→ OPEN WEB DASHBOARD ←" with arrows
- Full-width, centered, bold uppercase
- Black background, white text
- Inverts on hover (white bg, black text)
- Hard to miss - positioned right after system info

This makes the dashboard much more discoverable while maintaining
the 60s technical datasheet aesthetic!
