ESLint: Use strict & stylistic @typescript-eslint rules

The reason for adding "strict: true" to tsconfig.node.json is
because without it, eslint now fails with the following errors:

    [philbates@fedora laravel-starter]$ pnpm run lint

    > @ lint /home/philbates/code/philbates35/laravel-starter
    > eslint . --ext ts,tsx --report-unused-disable-directives --max-warnings 0

    /home/philbates/code/philbates35/laravel-starter/vite.config.ts
      0:1  error  This rule requires the `strictNullChecks` compiler option to be turned on to function correctly  @typescript-eslint/prefer-nullish-coalescing
      0:1  error  This rule requires the `strictNullChecks` compiler option to be turned on to function correctly  @typescript-eslint/no-unnecessary-condition
