fix(cms): storefront renders sections for landing pages + fix nav URLs

Two critical fixes for POC site rendering:

1. Storefront content page route now selects template based on
   page.template field: 'full' → landing-full.html (section-based),
   'modern'/'minimal' → their respective templates. Default stays
   content-page.html (plain HTML). Previously always used content-page
   which ignores page.sections JSON.

2. Storefront base_url uses store.subdomain (lowercase, hyphens)
   instead of store.store_code (uppercase, underscores) for URL
   building. Nav links now point to correct paths that the store
   context middleware can resolve.
