Some of the things you listed are bad practices, some are bad outcomes. Change the bad practices (no version control, no beta environment, etc) and use them to prioritize and change the bad outcomes over time.
At least half of the stuff you listed will probably never change. Congrats! Being the senior person means becoming comfortable with people making objectively worse decisions than you would, and putting the structure and architecture in place so that it still works anyway. As a bonus, most of those “objectively worse” decisions can be really good and better suited for the team than your decisions would have been ;).
