feat: show scheduled parts in eoa twap

[kernelwhisperer]

Instead of querying only "discrete" parts, now we query candidates as well (scheduled).

Depends on cowprotocol/cow-programmatic-orders-api#7
Depends on cowprotocol/cow-sdk#1002

Part of FE-479 Show Sheduled parts for TWAPs for EOAs

Summary by CodeRabbit

Walkthrough

The TWAP hook now maps unconfirmed part orders as virtual open orders. Tests cover candidate replacement, parent status handling, pagination requests, and final-part detection.

Changes

TWAP virtual part handling

Layer / File(s)	Summary
Map unconfirmed parts as virtual open orders apps/cowswap-frontend/src/modules/twap/hooks/useEoaTwapPartOrders.ts	The hook derives isVirtualPart from unconfirmed status, passes it to status mapping, and maps unconfirmed SDK statuses to open orders.
Validate candidates and pagination apps/cowswap-frontend/src/modules/twap/hooks/useEoaTwapPartOrders.test.tsx	Tests cover candidate replacement, cancelled and expired parents, page selection, page size, and final-part detection from the API total count.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 8af8f

Scheduled EOA TWAP parts are now shown as virtual open orders until confirmed, with terminal parent states preserved. The covered behavior presents no remaining merge-blocking risk.

Great, thank you!

There is one nitpick: when an order/leg status is updated, the table blinks. But I will not block the PR with this issue, I'll open a task in linear to address this issue later.
