Bump express and brunch in /webapp

[dependabot[bot]]

Removes express. It's no longer used after updating ancestor dependency brunch. These dependencies need to be updated together.

Removes express

Updates brunch from 1.7.13 to 4.0.1

Release notes

Sourced from brunch's releases.

4.0.0

• Breaking: Require node.js 12.13 or higher
• Breaking: Remove node-browser-modules:
  • This part of Brunch shimmed well-known node.js built-in modules and provided them for browsers - such as buffer and util
  • It increased Brunch package size massively and the modules themselves were outdated
  • Now, if you need to use "node.js" module, install proper shim from NPM
  • NPM packages can be used as before, this change only affects built-ins

3.0.0

• Make config optional; and you could have it in package.json
• Build speed-ups up to 1.5x for some cases.
• Built-in webserver is now using serve-handler from micro(1) webserver. Custom webservers are unaffected.
• Breaking: Require node.js 10.16 or higher
• Breaking: Remove Bower and AMD support
• Breaking: Remove support for CoffeeScript brunch configs, emit a command that would compile coffee file to js
• Breaking: New node.js API - use brunch.build() from node without hassle
• Decrease package size by a huge amount:
  • Update Chokidar to 3.0
  • Remove or integrate many dependencies
  • Update dependencies to latest versions
