Code quality

• Improved code quality for the theme provider component (#2225):

  • updated type for theme prop to ThemeConfig to distinguish from the type Theme which is shared over context. A Theme contains only the logo properties, while ThemeConfig can contain a colors property.
  • converted ThemeProvider to use hooks
  • created symmetry in context between app provider and test provider
  • added better tests for default topBar colors
  • fixed an issue where colorToHsla returned HSLA strings instead of HSLA objects when given HSL or HSLA strings
  • fixed an issue with colorToHsla where RGB colors with no saturation could result in a divide by zero error
  • fixed an issue where colorToHsla inconsistently returned an alpha value
  • fixed an issue where lightenColor and darkenColor would lighten or darken absolute lightness values (0, 100)
