Update pricing table and billing configuration

Updated the pricing table component to display all line items for a plan, removed condition to exclude primary plan. Adjusted the type of a billing package in the sample configuration to be "metered" instead of "flat". Made related changes in line-item-details component to handle the changes in billing type and to fix the layout.
