migrate function/type/app tables to data_table_cpp_viz (issue 0081-J)

- Replace table_view() calls in draw_recent_functions, draw_apps_list,
  draw_analysis_list, draw_types_list, and vaults panel with
  data_table::render() via fn_table_viz static lib.
- Migrate Monitor sub-tabs Top Functions, Violations, Copied Code to
  data_table::render() with persistent State per panel.
- Keep Recent Executions and Failed Functions as custom ImGui tables
  (per-cell coloring + tooltips not supported by data_table).
- Layout-splitter tables (kpi_grid, chart_grid, monitor_kpi,
  proj_layout, explorer_layout) intentionally not migrated.
- CMakeLists: target_link_libraries(registry_dashboard PRIVATE fn_table_viz).
- app.md uses_functions += data_table_cpp_viz + full fn_table_viz stack.
