Dashboard Polish — Component Library + Cross-Page Consistency

What We Built

Final polish pass on the BrainstormRouter dashboard component library. Three key enhancements:

JSON Viewer — Collapsible tree component with syntax highlighting, copy-per-node buttons, and font-mono for all values. Auto-expands first 2 levels. Replaces raw
```
 blocks for structured data display in log details and forensic modals.
```

Stat Card Sparklines — Stat cards gain a sparkline slot (7-point mini SVG chart) and trend indicators (up/down/flat arrows with labels). The sparkline renders as a lightweight SVG path with accent color.

Data Table Sticky Headers — All data tables now use position: sticky headers that remain visible while scrolling through large datasets.

Why It Matters

Component consistency is the final step before the dashboard is investor-demo ready. The JSON viewer transforms raw JSON dumps into navigable, copy-friendly trees. Sparklines give stat cards immediate trend context. Sticky headers prevent the "where am I?" problem in long tables.
