Refine PackageDetail header + section hierarchy from review

PackageDetail:
- Warm header band (surface.warm) with "Package" overline, h3 name,
  h5 price in brand colour — creates distinct decision zone
- Section headings bumped to h6 (16px/600) — clear hierarchy vs
  LineItem body2 (14px/500)
- Divider + subtext before Extras: "These items can be added to your
  package at additional cost"
- Top padding increased, content padding increased (py: 3)
- Remove redundant textTransform/letterSpacing on overline (P2 fix)

LineItem:
- Item gap increased in PackageContents story (12px → 16px)

Audit: 19/20 (Excellent). 0 P0, 0 P1.
