Subject: [PATCH 1/2] feat: Add hexadecimal color input to color picker (fixes
 #3381)

Add a hexadecimal input field to the color picker component, allowing
users to input colors using hex notation (e.g., #FF5500) in addition
to the visual palette.

Changes:
- Add satus.color.rgbToHex() function for RGB to hex conversion
- Add satus.color.hexToRgb() function for hex to RGB conversion
  - Supports both full (#RRGGBB) and shorthand (#RGB) notation
- Add hexadecimal input field to color picker modal
  - Input syncs with palette, hue slider, and color preview
  - Palette and hue slider update hex input when changed
- Add CSS styles for hex input container, label, and input field
- Add unit tests for color conversion and UI components

The hex input provides a more precise way for users to input specific
colors, especially when copying colors from design tools or websites.
