Subject: [PATCH] Fix empty ExtraProperties cells in AbpExtensibleDataGrid

The implicit DisplayTemplate context caused the Razor source generator
to compile 'context.Item as IHasExtraProperties' into
'context as IHasExtraProperties' (dropping the .Item access). Since
CellDisplayContext<TItem> itself does not implement IHasExtraProperties,
the cast was always null and the cell rendered empty.

Renaming the context with Context="rowContext" produces the correct
'rowContext.Item as IHasExtraProperties' codegen and the cell now
shows the property value.
