Description

Add UI messages when PTC is enabled and battery is allowed to charge from grid. Should work for all FOM and BTM battery configurations including hybrids.

To test:

1. Create a case with any battery configuration.
2. On the incentives page set the state or federal PTC to a non-zero value and non-zero term. (Should work with single value or annual values.)
3. On the Battery dispatch page, choose any dispatch option and enable grid charging.

The battery dispatch page should display a pop-up window with a message. The Incentives page should show a red message near the PTC inputs.

Note that for manual dispatch, the pop-up window appears every time check "enable grid charging" for different periods -- a bit annoying, but I think acceptable.
