There is no more webapp/app/static/vendors. Rather there's a webapp/app/static/node_modules, which is a symlink to webapp/node_modules. To install all frontend packages needed, you need to npm install, the dependencies are in webapp/package.json. npm install is now done in webapp/run.sh.
No page uses a CDN anymore, those have all been moved to be locally under NPM as well.
I first did the above two steps while maintaining exact version parity with the old vendors stuff, but the last commit relaxes the versions a bit, e.g. 2.6.3 becomes ^2.6.3. Nothing seemed to break, but wouldn't hurt if others check too.
I removed a few dependencies which we didn't seem to be using. There's still a couple I'm unsure if we use (plugins of datatables.net).
There are some other, unrelated clean-up items that I did on the way.
I expected many of the packages we use to be very far behind their latest development, but it's actually not that bad. We use jquery 2 and bootstrap 3, which have been superseded by jquery 3 and bootstrap 4 and 5. At least with bootstrap 5 it's a whole new world and we shouldn't upgrade. Didn't look into jquery 3 and bootstrap 4 in detail, but bootstrap 3 is still getting security support, so could stick with that. jQuery 2 has been unsupported for 5+ years, not sure how serious that is. All other packages we seem to be at the latest major version number.
