feat: adopt Apple-style glassmorphism UI from logistics project

Three-tier glass system (glass-underlay, glass-capsule, glass-chip),
pill-glass capsules with inner shine for header nav pills,
two-layer header backdrop with fade mask, solid white left panel
and juicy rounded-t-3xl bottom sheet for map interactions,
bold/black headings throughout.
