Update site headers, buttons, and pricing table format

The changes made are primarily related to updating the layout and style of the site headers and buttons. A significant chunk of modifications were made to the pricing-table.tsx file, including tweaks to the styling, padding, highlighting, and addition of new properties. Also, the site-header-account-section.tsx and site-page-header.tsx files have seen a few changes, focusing mainly on buttons and heading style. A new locale message was added to facilitate better user interaction.
