feat(acadenice): add graph view UI for R3.5.2 (58 tests, Patch 013)
Frontend knowledge-graph page at /graph. Force-directed canvas via
react-force-graph-2d (lazy-loaded, falls back to placeholder when lib
absent). Controls sidebar: space filter, edge-type checkboxes, depth
slider 1-5, include-orphans toggle, node search, stats, truncated
banner. Side panel Drawer on node click: title, space, in/out degree,
open-page CTA. Jotai atoms for cross-component state. React Query
hook with 300ms debounce. Interactions: zoom/pan/drag, click->side
panel, double-click->navigate, right-click->focus, Esc/F keyboard.
Upstream patches: +route /graph in App.tsx, +Graph nav entry in
global-sidebar, +24 i18n keys FR+EN.
New deps (not installed): react-force-graph-2d, d3-force.
Completes R3.5 entirely.
