fix(frontend) :: take browser dependencies from npm

[81reap]

build.rs downloaded Tabler, ApexCharts, Tom Select and the Tabler icon sprite via CDN on every clean build. This came with its own retry loop and cache under target/.

Now we rely on npm to install 3rd party libs and update /* !include */ markers to point at node_modules instead of a URL. This comes with the benifit that the rust build does not need network anymore, but does require npm ci for a clean build.

This should not be merged alone otherwise it will break the crates.io tarball. The next commit in the stack addresses this.

Hi! Can you please organize the PRs so that all are small enough to be reviewed, yet none breaks the project?

[81reap]

@lovasoa not sure how to do both here. I chose to split up this and #1457 as the diff was getting quite big.

That said, with GitHub stacks, we can review both PRs and merge them together so that project is never in a broken state!

It looks like the next pr contains changes unrelated to what you are doing here.

I think you could make a good no-brainer pr with net negative lines of code by keeping the exact exact same output files, but removing the include comment mechanism, hardcoding the concatenation logic in build.rs and copying from node modules instead of the web.
