Add EPUB upload + DB integration

Add server-side EPUB import and integrate Prisma + Mongo for novels/chapters. Introduces a new moderator API route (app/api/mod/epub/route.ts) that parses .epub files, creates a novel record in Prisma, and inserts chapter documents into MongoDB via the Chapter Mongoose model. Frontend: novel management UI now supports EPUB upload (app/mod/truyen/novel-client.tsx) with progress/toasts and preserves the manual 'Add novel' dialog. Convert app pages to fetch real data from Prisma and Mongo (app/page.tsx, app/truyen/[slug]/page.tsx, app/truyen/[slug]/[chapterId]/page.tsx), adapt types/props to use authorName, and adjust chapter/comment IDs to use Mongo _id strings. Minor fixes: TTS player logs playback errors, UI text fixes (e.g. "Chương"), and novel-card/other components updated for authorName. package.json updated with epub2, html-to-text and types; pnpm lock updated. Adds tsconfig.tsbuildinfo.
