This PR removes the following dependencies

• babel: all now works directly on ESM, no extra transpilation necessary
• express (and also cookie-parser, cors): nuxt3 comes with nitro/h3, no need for express
• cssesc: was anyway not needed anymore

not included (potential future PRs):

• some further code simplification would now be possible with nuxt3. Didn't include it in this PR, to avoid making the PR larger than it already is.
• moving from axios to a more generic fetch API (separate topic + needs adjustments on hal-json-vuex side)

open points

• release hal-json-vuex v3-alpha
• sentry reporting
• check if all npm packages are still needed
• check if transpilation of vue-icon and colorjs is still needed
• fix i18n middleware to set language
• general cleanup (removal of comments, old code, etc.)
• dayjs doesn't like rollup: locales are not removed by tree-shaking when building the app

Fixes #4072
