Make entire UI mobile-friendly with responsive breakpoints

Add media queries at 480px/768px across all components: single-column
dashboard cards on phones, progressive table column hiding, smaller
typography, reduced padding, full-width toggle buttons, and compact
header. Desktop layout unchanged.
