refactor(complianceCheckTab): split — DOCUMENT_TYPES + Storage + Polling out

ComplianceCheckTab.tsx war 519 LOC und blockte jeden weiteren Edit
(500-LOC-Hard-Cap). Drei Concerns ausgelagert:

  - _document_types.ts: DOCUMENT_TYPES + DocTypeId (inkl. news doc_type)
  - _compliance_storage.ts: STORAGE_KEY_*, DocState/HistoryEntry types,
    emptyDocState/initState helpers, countWords
  - _useCompliancePolling.ts: Resume-Polling-Hook (importierbar,
    Inline-Polling bleibt für Stabilität)

ComplianceCheckTab.tsx ist jetzt 461 LOC (-58).
