fix: dbDelta separate tables, add SEOHead for page titles

1. License table creation:
   - dbDelta requires separate calls per CREATE TABLE
   - Split into sql_licenses and sql_activations
   - Added 'PRIMARY KEY  (id)' with two spaces (dbDelta requirement)

2. Page titles:
   - Added SEOHead to Cart page (title: Shopping Cart)
   - Added SEOHead to Checkout page (title: Checkout)
   - Shop already had SEOHead

3. usePageTitle hook created (alternative to SEOHead for non-Helmet usage)
