PR-227028: update dependencies, migrate to TypeScript 6 and ESLint flat config

- Bump all dependencies to latest (React 19.2.7, Storybook 10.4.3, Webpack
  5.107.2 + webpack-cli 7, Jest 30.4.2, Cypress 15.17.0, Babel 7.29.7,
  sass-loader 17, css-minimizer-webpack-plugin 8, eslint-webpack-plugin 6).
- Migrate TypeScript 5.9 -> 6.0.3: set tsconfig rootDir, add
  ignoreDeprecations "6.0", scope include to src/components + src/@types, and
  declare *.scss/*.sass/*.css modules for stricter side-effect imports.
- Switch @babel/preset-react to the automatic JSX runtime and drop redundant
  React imports in stories and tests.
- Migrate ESLint from the deprecated .eslintrc.js to flat config
  (eslint.config.mjs) using typescript-eslint, @eslint/js, globals and the
  React/Storybook plugins. Keep ESLint at v9 because eslint-plugin-react does
  not support v10 yet. This fixes the previously broken lint (missing
  @typescript-eslint parser/plugin) and normalizes formatting.
- Fix a latent bug in .storybook/main.js (comma instead of semicolon joining
  two assignments via the comma operator).
- npm audit fix: 0 vulnerabilities.
- Bump package version to 1.4.0.
