📝 Walkthrough

Walkthrough

The PR upgrades UI dependencies, migrates foundation imports, centralizes Sentry setup, lazy-loads routed components with loading fallbacks, and updates production webpack optimization.

Changes

Application modernization

Layer / File(s) Summary
Foundation dependency and import migration
package.json, src/components/..., src/pages/..., src/app.js
The foundation package is upgraded. MUI date pickers and Formik are added. Foundation components now use direct module imports.
Sentry initialization and error boundary
src/app.js, src/components/SentryErrorBoundary.js, src/sentry-init.js
Sentry setup moves into initSentry. SentryErrorBoundary captures errors, initializes Sentry when a DSN exists, and renders the application within an error boundary.
Lazy route loading and loading fallback
src/layouts/*
Layout routes now use React.lazy and Suspense with AjaxLoader fallbacks. Existing routes, redirects, Redux mappings, and lifecycle logic remain in place.
Production chunk and minimization configuration
webpack.prod.js
Production builds now use hashed chunk filenames, parallel Terser processing, reserved lock names, and explicit minimization.

Estimated code review effort: 4 (Complex) | ~45 minutes

Mergeability Score: 🟡 Moderate · up to b2c41

This change may prevent the application from installing with the declared React version and can crash users who follow the missing-speaker redirect, so the PR is not merge-ready until these issues are fixed or explicitly accepted.

Use a React-compatible date picker.

The lockfile resolves React and React DOM to 16.14.0, but @mui/x-date-pickers@9.0.2 requires React and React DOM ^17.0.0 || ^18.0.0 || ^19.0.0. Upgrade both packages or select a date picker that supports React 16.
