Maintain the npm build environment

[odungern]

GitHub Copilot advises to migrate from vue/cli to Vite, as the former is in maintenance mode and could be deprecated in the future.

When compiling, the message is shown

• (node:25096) [DEP0040] DeprecationWarning: The punycode module is deprecated. Please use a userland alternative instead.

When doing 'npm install' with the current 'package.json', the following warnings appear:

• npm warn deprecated inflight@1.0.6: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
• npm warn deprecated @babel/plugin-proposal-class-properties@7.18.6: This proposal has been merged to the ECMAScript standard and thus this plugin is no longer maintained. Please use @babel/plugin-transform-class-properties instead.
• npm warn deprecated @humanwhocodes/config-array@0.5.0: Use @eslint/config-array instead
• npm warn deprecated stable@0.1.8: Modern JS already guarantees Array#sort() is a stable sort, so this library is deprecated. See the compatibility table on MDN: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort#browser_compatibility
• npm warn deprecated consolidate@0.15.1: Please upgrade to consolidate v1.0.0+ as it has been modernized with several long-awaited fixes implemented.

• npm warn deprecated @humanwhocodes/object-schema@1.2.1: Use @eslint/object-schema instead
