fix: clarify checkout step loading copy

[superdav42]

Summary

• Show “Recording Your Responses...” while a multi-step checkout advances before the final step.
• Keep the existing “Provisioning your site — this can take up to 60 seconds.” copy for the final checkout step.
• Expose the step-state/loading-copy variables and add regression coverage for the distinction.

Verification

• vendor/bin/phpcs inc/checkout/class-checkout.php tests/unit/Checkout_Step_Fields_Test.php
• vendor/bin/phpunit --filter Checkout_Step_Fields_Test
• eslint assets/js/checkout.js --ignore-pattern '*.min.js' (via local hook/lint-staged during commit)

📝 Walkthrough

Walkthrough

This PR adds step-specific loading messages to the checkout flow. The backend now exposes an is_last_step flag and localized recording_responses copy, allowing the frontend to display appropriate status text—"Recording Your Responses…" for intermediate steps and "Provisioning your site…" for the final step. Tests verify the step-dependent behavior.

Changes

Step-Specific Checkout Loading Messages

Layer / File(s)	Summary
Backend: Step-aware checkout variables and translation inc/checkout/class-checkout.php, lang/ultimate-multisite.pot	Backend checkout class adds is_last_step boolean and recording_responses i18n key to the checkout variables dictionary returned to JavaScript. Translation catalog entry supports the new localized message.
Frontend: Conditional loading message rendering assets/js/checkout.js	JavaScript conditional selects between "Recording Your Responses…" and "Provisioning your site…" loading messages based on the wu_checkout.is_last_step flag when the checkout form is submitted.
Tests: Step-specific loading behavior validation tests/unit/Checkout_Step_Fields_Test.php	Test fixture helper build_checkout_variables() constructs step-specific checkout variables. New test asserts account and payment steps produce different is_last_step values and loading copy.

🐰 A rabbit checks out with style,
Step by step, mile after mile,
"Recording responses" on the way,
"Provisioning soon!" at journey's day,
Loading messages, clear and bright,
Makes the checkout flow just right! ✨
