Add Obsidian Wrapped feature (inside-LMS, client-side vault parsing)

- WrappedRun Prisma model + migration (aggregates only, no note names/text)
- /wrapped authed route: FSA + webkitdirectory + drag-drop reader, Web Worker parser
- archetype + score heuristics, ДС-2 result card
- POST /api/wrapped/run (userId from session), public /share/wrapped/[token]
- next/og OG image (Satori+resvg-wasm, alpine-safe) + Fira Mono ttf
- middleware: /share/wrapped public
