chore: upgrade to react 19 react-to-print v3

[saurabhraghuvanshii]

Notes for Reviewers

package.json

Dev command fixed

• From old: webpack-dev-server -d --progress --colors
• To new: webpack serve --progress --color
• Why: old flags/options are not valid with current webpack CLI.

###React ecosystem upgraded

• react -> 19.x
• react-dom -> 19.x
• Why: keep your repo modern and avoid peer conflicts in other repos.

react-to-print upgraded

• 2.15.1 -> 3.3.0
• Why: old version caused peer dependency warnings and was not ideal with latest React.

ajv added in devDependencies

• Why: fixes webpack/schema-utils runtime mismatch (ajv/dist/compile/codegen errors).

examples/Router/index.js

Migrated router API

• Replaced old Switch + withRouter
• With new Routes, useNavigate, useLocation
• Why: required for react-router-dom v7.

Updated route syntax

• Old component/render props -> new element prop
• Why: modern Router API expects this format.

Kept class component working

• Added small wrapper (RoutedExamples) to pass navigate and location into class component
  -- Why: class component can’t directly use hooks.

Made mount target safer

document.getElementById('app-root') || document.getElementById('root')
Why: avoids blank page if one id is missing.

src/components/TableToolbar.js

Print feature was updated for new react-to-print version.

• Old print implementation replaced

• Removed old ...
  Added useReactToPrint with a small helper component PrintTableButton
  -- Why: v3 uses hooks API instead of old render-prop API.
  Runtime crash fix

useReactToPrint({}) instead of useReactToPrint()
Why: v3 destructures options; undefined caused:
Cannot destructure property 'bodyClass' of 'undefined'
