Show Quickpay operation history on the admin order view

[loevgaard]

Fixes #105

What it does

Each Quickpay payment on the admin order view gets a live operation history panel: every operation (type, amount formatted in the payment's currency, qp_status_code + qp_status_msg with the acquirer message as tooltip, pending label, timestamp), the captured balance, and a test-mode badge. No storage, no entities, no migrations — 2.x's scalar quickpayPaymentId is enough to fetch everything on demand.

Deferred, never blocking the order page

• The panel is a sylius_ui block prepended onto sylius.admin.order.show.payment_content (guarded by hasExtension('sylius_ui')) — it renders only a placeholder for payments carrying a quickpayPaymentId; payments without one get no panel at all
• A small inline script fetches GET /admin/quickpay/payments/{id}/operations after page load (auto-load with retry, per the issue's suggested default); the /admin path puts the route under the standard Sylius admin firewall/access control
• Controller/Admin/PaymentOperationsAction resolves the api key from the payment's own gateway config (with the 1.x apikey fallback), fetches via the 5s-capped Quickpay/ClientFactory from Validate Quickpay credentials from the gateway configuration form #106, and renders the partial — any failure returns 502 with an inline notice + retry link, and the retry re-fetches just that payment's panel

Verified

• Unit: 5 new tests — the happy path drives a real PaymentsEndpoint + Valinor mapper over a realistic snake_case payload (so the DTO mapping is exercised, not stubbed), plus unreachable-API → 502, unknown payment → 404, no quickpayPaymentId → 404, and the extension prepend. 73 tests, PHPStan (cold), ECS, Rector green.
• Live in the test app: the order page renders instantly with the placeholder, the fetch hits the real Quickpay API server-side (401 with dummy credentials) and the panel swaps to the inline error with a working Retry link — the failure-state UX end to end. lint:container, lint:twig (4 templates), lint:yaml (32 files), debug:router all green.

Labels/messages are translated in all 16 shipped locales (12 new ui.* keys).
