Neovim, switch to nixvim and mono file

This merges all the different files into one app.nix using nixvim
instead of the manual home-manager nvim management.

Behavior should be almost unchanged, with the following changes:
- Plugins now have defaults for my own personal sane default experience
- The highlighted line is now 81 instead of 80
- Treesitter plugins may not be integrated correctly
