Since packr have been deprecated in favor of go:embed for quite some
time now I have replaced it with plain go:embed functionality which
makes it more future proof.
The only downside is that go:embed can use relativ paths only, that's
why I have moved the web/dist folder into api/public.
Besides that I have refactored the static asset handling which includes
basic last modification and cache control headers to improve the cache
cache behavior for static assets.
It doesn't otherwise build on windows since by default it's `1`:
```powershell
Taskfiles versions should match. First is "2" but second is "1"
```
