docs: embed captured screenshots into the wiki pages Replace the 28 screenshot-placeholder lines with inline image embeds (keeping their captions) across Home, Getting started, Features, Tests & Practice, Flashcards, and Supabase Sync. The 7 screenshots that still need a human or live services keep a clearly-marked 'manual capture' note linking to the Manual Capture guide. Screenshots.md: update the intro to describe the embedded-image convention (markers now mean 'still needs capture') and the exact steps to add a screenshot (embed + flip the checklist row).
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.
