style: enhance toolbar with glassmorphism and improved design

- Add white background with subtle gray border and rounded corners
- Remove initial drop shadow, add shadow on hover
- Reduce vertical padding for more compact design
- Update button hover states to use darker gray
- Add sticky positioning with gap from top
- Improve responsive padding and animations
