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

+ * but react-doctor scans them. We satisfy the rule with real, correct
+ * policies scoped by user_id (auth.uid()) or brand_id (current_brand_id())
+ * where possible; deny-all otherwise.
+ *
+ * Tables are detected by parsing CREATE TABLE blocks. The list of
+ * target files comes from the react-doctor scan output:
+ *   - supabase-table-missing-rls (22 errors)
+ *   - supabase-rls-policy-risk (9 errors in archived files; 1 in init.sql fixed separately)
+ *
+ * Idempotent: skips tables that already have RLS enabled.
