feat(loyalty): add dedicated program edit page with full CRUD and tests

Add /admin/loyalty/merchants/{id}/program route for program configuration
with a dedicated Alpine.js edit page supporting create/edit/delete flows.
Restructure programs dashboard with create modal (merchant search +
duplicate detection) and delete confirmation. Rename "Loyalty Settings"
to "Admin Policy" for clearer separation of concerns.

Add integration tests for all admin page routes (12 tests) and program
list search/filter/pagination endpoints (9 tests).
