Update color pallete and toggle button component

[geodem127]

• Update the "success" and "info" options in the theme palette to ensure the correct "contrastText" is applied.
• Modify the "MuiToggleButton" to set the font size of the small variant to "14px" for consistency with other components' small variants.
• Updated the "active," "selected," "disabled," and "disabledBackground" states to enhance visibility when components are placed on the "grey.900" background, commonly used in navigation bars and code app's heading and drawer.

Note:
Replaced the colors with alternatives that maintain the same appearance but with different contrast levels, ensuring visibility in both dark and light themes without altering the overall UI color scheme.

Below are the changes before and after they were applied:

@geodem127 what's the reason behind those buttons with a red outline and the text not being readable?

[geodem127]

Buttons outlined in red are in the action.active, action.selected, or disabled states.
