* fix: enable scrolling in node editor panel sidebar
Add min-h-0 to flex containers in the ancestor chain so overflow-y-auto
actually triggers instead of content overflowing off-screen.

* fix: constrain tree editor page height to prevent panel overflow
Add overflow-hidden to TreeEditorPage root and NodeEditorPanel container
so the flex height chain is properly constrained by the CSS Grid cell,
preventing the node editor sidebar from growing beyond the viewport.

* fix: resolve lint errors in NodeEditorPanel and useTreeLayout

* fix: use viewport-based height for node editor panel
Replace h-full with calc(100vh - 105px) to bypass the CSS height chain
that fails to constrain the panel across browsers. The 105px accounts
for the topbar (56px) and editor toolbar (49px).

* style: fix canvas controls visibility and enhance dot grid background
- Add !important to all React Flow dark theme overrides to ensure they
win over library default styles (fixes white controls rectangle)
- Add SVG fill inheritance for control button icons
- Use slightly lighter canvas background (bg-accent/30) so dot grid
is more visible
- Increase dot size and use muted-foreground color for better contrast

* feat: collapse sidebar categories with show more/less toggle
Show only the first 4 categories by default with a "N more" button
to expand the full list. Reduces sidebar clutter when many categories
exist.
