Initial commit: Converge portfolio rationalization app

Next.js app for mapping a customer's competitive tool landscape onto our
portfolio and building the consolidation business case: assessment
workbench, customer report and Word export, product catalog, competitive
knowledge base, dossier import, shareable landscape questionnaires with a
review inbox, tool-footprint and business-unit value analysis, and an
implementation timeline.
