💡 Improve Commenting Feature with Additional Navigation Options

### Area

Proposal Pillar

### Is there new design needed?

No

### What?

Introduce two small updates to enhance the **commenting feature** in GovTool:
1. Add a **"See All Comments"** button next to the **"+ Reply"** button in the comments section of any proposal.
2. Make the **comment icon** clickable to navigate users directly to the **comments section**:
- On the **Proposal Details** page.
- On the **All Proposals** page (each proposal card).

### Why?

- Improves user navigation and accessibility for viewing comments.
- Provides a clear entry point for users who wish to browse all comments instead of replying directly.
- Enhances discoverability of the comments section, especially from the **All Proposals** page.

### How?

- Add a **"See All Comments"** button next to the existing **"+ Reply"** button.
- Update the **comment icon** to be clickable, linking directly to the comments section on both:
- **Proposal Details** page.
- **All Proposals** page (each proposal card).
- Ensure smooth scrolling behavior for the clickable comment icon to improve user experience.

### (Optional) User Story with acceptance criteria

- [ ] A **"See All Comments"** button is added next to the **"+ Reply"** button in each comments section.
- [ ] The **comment icon** is clickable and navigates to the comments section on:
- [ ] The **Proposal Details** page.
- [ ] The **All Proposals** page (each proposal card).
- [ ] Navigation behavior is smooth and intuitive.
