*: replace nxt -> monogon

These are hopefully the last leftovers from the nxt monorepo.

This change breaks existing build containers and IntelliJ setups, and
unfortunately thrashes developer workstation Bazel caches.

Running `scripts/bin/destroy_container.sh &&
scripts/bin/create_container.sh` and then following the IntelliJ setup
guide in //README.md should be enough to fix everything.

Did that locally and was able to set up a fully working IntelliJ
IDE against this change.
