Replacing ‘activity’ on budget type with this—they should come from a
user’s role rather than the activity. Going with a generic name though
so this can change over time.
Add a TimeBudget model which allows a job to have a time budget for each
activity type. We’re allowing nil as a holder for a generic budget,
though there’s currently no way to use that.
We automatically delete any time budgets which are set to zero.
