Migrate dashboard module to React 19

[devin-ai-integration]

Summary

Ports the AngularJS dashboard page module (src/app/pages/dashboard/) to React 19, rendered inside the existing AngularJS shell via a bridge directive. The UI-Router dashboard state now uses template: '<dashboard-react></dashboard-react>' instead of templateUrl: dashboard.html + the directive-based widgets.

All 8 dashboard widgets are reimplemented as React components under src/app/react/pages/ and composed by DashboardPage in the same Bootstrap grid / ba-panel layout (via the shared <Panel> component):

• DashboardPieChart — 4 easyPieChart widgets (jQuery plugin init in useEffect)
• TrafficChart — Chart.js doughnut on #chart-area + channel legend
• DashboardMap — AmCharts world map on #amChartMap
• DashboardLineChart — AmCharts serial chart on #amchart
• PopularApp — static "Most Popular App" widget
• BlurFeed — 11 feed messages, click-to-expand
• DashboardTodo — add (Enter / plus), check, remove; stable IDs as keys
• DashboardCalendar — jQuery FullCalendar on #calendar

Key points (non-obvious from the diff):

• Theme injection: the bridge directive (dashboardReact.js) injects baConfig, layoutPaths, baUtil via Angular DI and passes them as React props — never read from window. Derived colors use the shared colorHelper mix() algorithm (e.g. doughnut hoverBackgroundColor), not hardcoded hex.
• Lifecycle: every chart/jQuery-plugin useEffect returns a cleanup (chart.destroy() / .clear() / fullCalendar('destroy')); the bridge unmounts the React root on Angular $destroy.
• DOM fidelity: widget custom-element tags (<dashboard-pie-chart>, <popular-app>, …), CSS classes, and element IDs are preserved so the framework-agnostic Playwright suite keeps passing.
• Build wiring: gulp/inject.js excludes src/app/react/** (ES modules bundled by webpack, not standalone scripts), gulp/server.js serves build/react/, index.html loads bundle.js, and gulp/build.js gains a copyReactBundle task. The rebuilt webpack bundle is committed at build/react/bundle.js.

Verification

e2e/dashboard.spec.ts — 34/34 passing against the React build (gulp serve:e2e + Playwright). Tests were not modified.
