ℹ️ Issue

Closes #201

📝 Description

Write a short summary of what you added. Why is it important? Any member of C4C should be able to read this and understand your contribution -- not just your team members.

Implemented a cost-benefit analysis feature in the frontend. Staff member inputs their hourly rate and the time per report and the feature calculates the net benefit of pursuing the grant. It's important so that staff members know which grants are worth pursuing.

Briefly list the changes made to the code:

1. Created cost benefit component (includes auto reset after closing expanded grant view)
2. Integrated cost-benefit design next to description box
3. Integrated cost-benefit display in the grant header next to Timeline and Amount
4. Implemented state lifting to display calculated net benefit in the grant header
5. Fixed notification popup scroll bar (removed scroll bar) for cleaner UI

✔️ Verification

What steps did you take to verify your changes work? These should be clear enough for someone to be able to clone the branch and follow the steps themselves.

I tested the feature as a user would. I manually checked calculations when time per report changes, hourly rate changes, and verified that this showed the correct number in both the "Analysis" section and "Cost-benefit" section. I closed expanded grant view and reopened to ensure that changes clear. Tested with different grants to ensure calculations are correct.

Provide screenshots of any new components, styling changes, or pages.
