+Removes default React imports from template files, aligning with the requirements for the upcoming React 19 migration. Introduces a new ESLint rule to disallow `import React from 'react'` and `import * as React from 'react'`. Updates the `tsconfig` compiler option `jsx` to use `react-jsx` instead of the legacy `react`.
