fix: improve page transition consistency and Safari safe-area handling

[milkevich]

Summary

• Simplifies built-in page transition easing and timing for more consistent enter and exit animations.
• Reduces the blur transition from 20px to 10px to improve rendering performance.
• Updates slide, spin, rotate, push, and pull timing values.
• Removes the mobile-only fade fallback from the shared elements lab so the configured blur transition is used consistently.
• Adds a header pseudo-element that fills Safari’s top safe area while preserving the transparent header effect.

Validation

• npm run check
• Tests cover new or changed behavior
• Public documentation matches verified behavior
• Public API and package contents were reviewed
• Visual styling and layout are unchanged unless required by the change
