feat: modernize UI with glassmorphism aesthetic

Apply iPhone-style frosted glass effects throughout the app:
- Updated theme variables with enhanced blur and opacity
- Applied backdrop-filter blur effects to all panels and cards
- Modernized header, buttons, and interactive elements
- Added glass styling to chat bubbles, input fields, and brain process cards
- Improved shadows and glow effects for visual hierarchy
- Added dark mode support with appropriate glass colors
- Smooth cubic-bezier transitions for polished interactions

All layout and functionality remain unchanged; this is purely visual modernization.
