fix(loyalty): align menu item IDs with URL segments for sidebar highlight

The store and merchant init-alpine.js derive currentPage from the URL's
last segment (e.g., /loyalty/program -> 'program'). Loyalty menu items
used prefixed IDs like 'loyalty-program' which never matched, so sidebar
items never highlighted.

Fixed by renaming all store/merchant menu item IDs and JS currentPage
values to match URL segments: program, cards, analytics, transactions,
pins, settings — consistent with how every other module works.

Also reverted the init-alpine.js guard that broke storeCode extraction,
and added missing loyalty.common.contact_admin_setup translation.
