feat(login): overhaul login experience

* simplify login menu, making it more accessable to newcomers and
  easier to select remote signer options
* enable `ngit login` to work from anywhere (not just a git repo)
* assume fresh login details saved to global git config but fallback
  to local repository
* maintain local repository login via `ngit login --local`
* maintain login via CLI arguments eg `ngit send --nsec nsec123`
* nudge users to remember nsec when pasting in ncryptsec for a
  better UX, whilst maintaining the option to be prompted for
  password everytime
* create placeholder menu items for help menu and create account
