fix: align portfolio-hub ledger write adapter to live API contract

REQ-017 CHG-20260606-01. Live portfolio-hub returned 404 for the
trex-orbit-assumed POST /v1/assets/{asset_id}/ledger/trades. Correct to
POST /v1/portfolios/{portfolio_id}/ledger/trades with body keys
quantity/fee_amount/tax_amount (was qty/fee/tax), success 201. Reverified
with live e2e (201 Created, outbox COMPLETED) + durability drain of the
prior 404'd item. Resolves the REL-001 ledger-write release blocker.

 ## Key Decisions
 1. `asset_id == portfolio_id`: 슬롯의 `portfolio_id` 를 ledger path param 으로 직접 사용한다. 매핑 조회나 asset master 동기화는 후속 범위다.

+- 트리거: RabbitMQ 매수 인텐트 → 체결 → ledger 기록 실 e2e 중 ledger write 가 live portfolio-hub 에서 404 발생. 원인은 어댑터가 구 orbit 가정 계약(`POST /v1/assets/{asset_id}/ledger/trades`, body `qty`/`fee`/`tax`)을 사용한 것. 실 계약은 openapi `LedgerTradeRequest` 기준 `POST /v1/portfolios/{portfolio_id}/ledger/trades` + `quantity`/`fee_amount`/`tax_amount`(성공 201).
