Move work email config to separate work.nix file in email directory,
remove the if block dependencies on mu status since that doesn't get
update if mu.enable is changed in another file!
Outlook update seems to have broken davmail outside the VPN, so
removed from personal computers.
Removed accountEnabled let var and just tie account activation to mu
status.
Move git, starship and btm expressions to own files
Move account dir expressions up a level, remove accounts dir
Clean up some unused expressions (like qutebrowser and firefox)
