feat: add C++ ImGui functions for core UI and visualization

Funciones C++/ImGui para dashboards (grid, panel, docking, sidebar, tabs), visualizaciones (candlestick, gauge, histogram, pie, sparkline, heatmap, scatter, line, bar, surface3d, kpi, table), grafos (force layout, renderer, viewport, spatial hash, types) y utilidades (time series buffer, tracy zones, memory/fps overlay, plot theme).
