Refactor diet energy calculation and update NEmf logic Refactored the calculation of dietary net energy concentration (NEmf) in Diet and FeedIngredient classes to use NEma and NEga properties with conversion and caching. Updated BeefCattleResultsService to handle cases where NEmf is not provided, calculating it from TDN when necessary. Improved property change notifications and method signatures for clarity.
