Add missing pipeline statuses to UI with Hebrew labels

Added analyst_verified, research_complete, analysis_enriched, and
ready_for_writing statuses across all UI components: status-badge,
workflow-timeline, status-donut, status-changer, status-guide, and
kpi-cards. Also changed qa_review label from "QA" to "בדיקת איכות".
