Align court auction lookup with monthly site search

The court auction notice page posts a YYYYMM search key from its 조회 button and returns a month of rows. Keep day inputs as a compatibility filter over the monthly response and normalize the current nested detail payload shape.

Constraint: courtauction.go.kr has no public API and blocks bursty automated calls.

Rejected: querying every day independently | the upstream search surface is month-based and day calls return false empty results.

Confidence: high

Scope-risk: narrow

Directive: Preserve the site-observed YYYYMM notice search contract unless the PGJ143M01 XHR changes again.

Tested: npm --workspace packages/court-auction-notice-search test; npm run ci; live 서울중앙지방법원 2026-05 notice/detail smoke lookup.

Not-tested: PR CI after push.

 ## Inputs
 
-- `date` — 매각기일 (YYYY-MM-DD 또는 YYYYMMDD). 필수.
+- `date` — 매각기일 월(YYYY-MM 또는 YYYYMM) 또는 특정일(YYYY-MM-DD 또는 YYYYMMDD). 필수. 실제 사이트 검색 버튼은 월(YYYYMM) 단위로 조회하므로 특정일 입력은 월 조회 후 해당 일자만 필터링한다.
 - `courtCode` — 법원사무소코드 (예: `B000210` = 서울중앙지방법원). 비우면 전체. `getCourtCodes()` 또는 `codes courts` 로 받아온다.
 - `bidType` — `date` (= 기일입찰, code 000331) 또는 `period` (= 기간입찰, code 000332). 빈값이면 둘 다.
 - `caseNumber` — 사건번호. `2024타경100001` 형식 권장. `2024-100001` 도 받아서 `2024타경100001` 로 정규화한다.
