DO NOT MERGE: Brand Evolution Colors

[brianacnguyen]

Description

This PR includes comprehensive updates to the dark theme design tokens as part of our brand evolution initiative. The changes focus on enhancing visual consistency and accessibility across our color system.

Key updates include:

1. Refined background colors and their hover/pressed states
2. Adjusted text and icon color hierarchy
3. Updated border colors for better contrast
4. Modified overlay colors for improved visibility
5. Enhanced semantic colors (primary, error, warning, success) and their states
6. Updated shadow tokens for better depth perception

The reason for these changes is to align our dark theme with our evolving brand guidelines while maintaining accessibility standards and improving overall user experience.
