Rate rises and charge code-based estimates

The estimate rate adjuster applies a little differently to estimates that are 'policed' via charge codes.

When the estimate contains charge codes the utility is not relevant or necessary. Adjustments happens automatically: when activity rates rise there is the same amount of money left in the estimate cost as before, so there is less time left for any updated activities, as seen in the first example below.

However, the estimate can contain activities even though it is policing via their charge codes. Here the estimate rate adjuster can update an estimate cost when the corresponding activity's rate rises.

Below very simple scenarios illustrate all this in practice.
