Documentation refresh: current features, corrected architecture, and screenshot pipeline Brings every wiki page up to date with the current app: corrected tech stack and storage model, removed the retired Microsoft 365 integration notes, added pages for tests & practice, flashcards, the student portal, a FAQ, a getting-started tour, and the screenshot capture pipeline (checklist + capture script + manual-capture guide). Screenshot checklist is pushed in the uncaptured state so the capture-wiki-screenshots workflow can capture and publish the PNGs.
