wolf: add tab-completion + clarify fix-ea-game is universal for EA titles

- install-completion: writes a bash completion script to
  ~/.bash_completion.d/manage-wolf and registers it, so double-tab
  after './manage.sh ' shows all available commands.
- fix-ea-game kept as general name (not fix-swbf2-2017): the EA Desktop
  registry key is shared across all EA games; the Valve has-run key
  follows the same EADesktopSetup pattern across EA's catalog.
