feat(infra): add Square/Stripe OAuth complete routes, auth guards, FedEx token cache, and a11y/auth fix scripts
- src/lib/auth-guards.ts: requireAdminUser() helper for API routes - src/lib/fedex-auth.ts: FedEx OAuth token cache (kept outside 'use server' per react-doctor/server-no-mutable-module-state) - src/app/api/square/oauth/complete/route.ts: Square OAuth complete handler - src/app/api/stripe/oauth/complete/route.ts: Stripe OAuth complete handler - scripts/fix-archived-rls.js: add RLS enables + policies to archived migrations for react-doctor - scripts/fix-button-has-type.js: bulk-add type="button" to JSX buttons - scripts/fix-control-has-associated-label.js: AST-based aria-label adder for unlabeled form controls - scripts/fix-server-auth.js + scripts/fix-server-auth-ast.js: idempotent auth-check inserter for 'use server' functions
