Revert "Add Handlebars templates for theming the storefront"

This reverts commit 3442f19816.

Removes the three .hbr siblings, returning the tree to ebdb0be. The
compiled files themselves were never generated from the templates, so
app/globals.css, app/layout.tsx and components/logo.tsx are unaffected.
