Multiple changes (cleanup, remove edison, add felixalbpc)

- Removes hold host edison
- Adds new host, felixalbpc, a work machine. This requires some cleanup
  to fit into the office network, use other SSH keys, etc.
- Clean up some package installs, putting more things into the common
  home-manager packages, rather than systemwide or host-specific homes.
- Various small changes like disabling Github Copilot on nvim startup.
