fix: map EIA fuel type codes to display names in generation chart

Browse Source 
EIA stores fuel types as codes (NG, NUC, WND, SUN, COL, WAT) but
the chart expected display names (gas, nuclear, wind, solar, coal,
hydro). All data was falling through to "other". Added EIA_FUEL_MAP
lookup in pivotGenerationData to resolve codes before categorizing.
