Fix case detail: document fields, expected-outcome label, drop debug note

Three user-reported bugs on /cases/[caseNumber]:

1. Documents tab showed "9 מסמכים" in the count but rendered nothing —
   DocumentsPanel was reading filename/category/status/size_bytes/uploaded_at,
   but the real FastAPI payload (case_get → db.list_documents) returns
   title/doc_type/extraction_status/page_count/created_at. Rewrote the
   panel against the actual document row shape, added a CaseDocument
   type alias in lib/api/cases.ts, mapped doc_type to Hebrew labels
   (כתב ערר / כתב תשובה / ...) and extraction_status likewise.

2. The "פעולות" tab showed a debug-flavoured paragraph "עריכת פרטי התיק
   נשמרת מיד דרך PUT /api/cases/1033-25" — that was internal wording,
   not user copy. Removed.

3. Overview tab showed the raw enum value "full_acceptance" in the
   expected-outcome line. Mapped through the existing expectedOutcomes
   label array so it now reads "קבלה מלאה".
