chore(examples): polish business-report + refresh showcase/README renders for SVG icons (#213)

Polish BusinessReportExample (heavier gold hero stroke, larger hero scene, asymmetric soft-panel corners) and refresh the committed README + web/showcase renders (PDF + thumbnail) for the templates whose output changed with the SVG-icon migration: cv-mint-editorial / monogram-sidebar / sidebar-portrait / timeline-minimal, the timeline-minimal cover letter, and business-report. Scoped to changed renders only.
