For a management role to be sustainable long-term, what estimated percentage of time should be dedicated to direct people/process management?

Answer

50% or above.

If the people/process management percentage is below 50% of a 40-hour week, the individual is likely still operating as an individual contributor with an extra title, which is unsustainable long-term.
