common/embed: replace all go:embed use by an embedded archive

Some of the files were quite big:

- asns.csv ~ 3 MB
- index.js ~ 1.5 MB
- *.svg ~ 2 MB

Use a ZIP archive to put them all and embed it. This reduce the binary
size from 89 MB to 82 MB. 🤯

This also pulls some code modernization (use of http.ServeFileFS).
