Update Tabs on My Actions Page According to New Design System

[Kale98]

As a user, I want the tabs on the My Actions page to follow the updated design system, so the page feels consistent with the rest of the platform and improves the user experience.

ACCEPTANCE CRITERIA:

• Tab Design Update: Apply the new design system to the tabs on the My Actions page, ensuring they are visually consistent with the rest of the platform.
• The design should reflect updates in: Typography (font size, weight), Color scheme (background, active state, hover state), Padding and spacing (for better alignment and usability).
• Tab Functionality: Ensure that all tabs remain functional and that switching between them is smooth and responsive. Maintain the current functionality (e.g., My Votes, Governance Actions) while adhering to the new design system.
• Responsiveness: The tabs should be fully responsive, adjusting properly across all device sizes (desktop, tablet, mobile) according to the new design system.
• Consistency: Verify that the tabs are visually and functionally consistent with the rest of the platform where the new design system has been implemented.
• Pages to Update: My Actions page: Ensure the new design is applied to all tabs on this page.
