Replace the hand-rolled SVG Sankey on the Cashflow page with a concentric multi-level donut (recharts), aimed at working on both desktop and mobile where the Sankey was wide and hard to use. - Backend: `sankey?nested=1` returns the full nested Income/Expense tree (up to MAX_DEPTH) via a new `CategoryTree::nest()`, strictly by category type so its totals match the summary and breakdown cards (savings, investments and transfers excluded). A synthetic "Direct" child keeps each node's children summing to the node total. - Frontend: `MultiLevelDonut` renders concentric rings — income grows toward the centre, expense toward the rim — with a `showIncome` prop exposed as a Combined / Expenses-only toggle for comparison. Inside labels on the innermost ring; leader-line labels (name + share) on the outermost ring with per-side vertical collision avoidance on wide screens, suppressed below 480px where the outer ring is read on tap. - Pure ring-building logic lives in `lib/donut-utils` with unit tests; the nested endpoint has a feature test. Prototype for comparing the Combined vs Expenses-only layouts before picking a final direction; the old SankeyChart component is kept but no longer rendered on this page. |
