fix: remove cash flow summary cards and restore area chart shading

Remove the 4 summary cards from the Cash Flow page as they don't
properly represent the story over time. Increase gradient opacity
on stacked area charts (cash flow and investment scenarios) from
0.3-0.4/0-0.05 to 0.6/0.15 for better visual shading.
