fix: update console deps (#9628)

# Which Problems Are Solved
Closes most of the dependabot alerts

# How the Problems Are Solved
Updating Versions as much as possible. Angular upgrade was left out on
purpose.

# Additional Changes
Some refactoring of unused code, which I stumbled upon looking at our
used deps.
