Redesign toolbar, palette, and dock UI

Toolbar:
- Compact project/MCM selectors always visible at top
- Action bar (SVG, JSON, Import, Clear) as compact button strip
- Cleaner section toggles with minimal chrome
- Inline settings rows (W/H and Grid/Gap on one line each)
- Narrower width (220px vs 240px)

Palette:
- Group headers are collapsible (start collapsed to save space)
- Small symbols (Controls, Sensors, I/O, Other) use 2-column grid
- Conveyance keeps list layout (wider items)
- Lighter, less cluttered item styling
- Custom scrollbar

Color scheme:
- Shifted from navy/red (#16213e/#e94560) to slate/blue (#111827/#3b82f6)
- Better contrast and more professional feel
- DeviceDock updated to match
