💡 Implement Infinite Scroll for Governance Outcomes Section

### Area

Other

### Is there new design needed?

Yes

### What?

Currently, in the **Governance Outcomes** section, additional proposals can only be loaded by clicking the **"Show More Actions"** link. This behavior is inconsistent with the **Live Voting** page, where new items load automatically when scrolling.

To improve user experience, proposals in this section should load automatically **when the user reaches the bottom of the page** instead of requiring a manual click.

### Why?

- Improves consistency with the Live Voting page.
- Enhances user experience by removing the need for manual loading.
- Makes navigation more seamless and intuitive.
- Reduces unnecessary clicks and interaction friction.

### How?

- Replace the **"Show More Actions"** button with an **infinite scroll** mechanism.
- Trigger automatic loading when the user reaches the bottom of the list.
- Ensure smooth and efficient performance without excessive load times.
- Validate that loading behavior remains responsive across different devices.
