fix: align logo and company name, reduce spacing

Alignment fixes:
- Remove gap: 40px from .header-nav (caused extra space)
- Add justify-content: flex-start to .header-logo
- Set logo img width: auto (prevent stretching)

Spacing reductions:
- Logo width: 120px → 100px
- Padding/margin: 16px → 12px
- Font size: 15px → 14px

Result:
- Logo left-aligned ✓
- Company name left-aligned (no extra gap) ✓
- Tighter spacing (saved ~20px) ✓
- Clean, professional layout ✓
