💡 Add Option to Edit and Remove Comments in Budget Proposal and Proposal Discussion Forum Sections

### Area

Other

### Is there new design needed?

Yes

### What?

Introduce the ability for users to **edit** or **remove** their own comments in both the **Budget Proposals** and **Proposal Discussion Forum** sections. This functionality should include a **time window** during which editing or removal is allowed (e.g., within 1 hour of posting).

### Why?

- Allows users to correct mistakes, typos, or improve clarity after posting.
- Prevents long-standing comments from being changed in ways that might disrupt context.
- Encourages better engagement while maintaining integrity of discussions.

### How?

- Add **edit** and **delete** icons next to comments posted by the currently logged-in user.
- Enable editing or removal **only within a predefined time window** (e.g., 1 hour).
- Display a small notice on edited comments (e.g., "edited").
- After the time window, editing and deletion should no longer be available.
- Apply the same logic across both **Budget Proposals** and **Proposal Discussion Forum** sections.

### (Optional) User Story with acceptance criteria
