refactor(core): remove printerz proxy and unused pdf dependencies

Remove the Printerz API proxy route, server-side endpoint, and local PDF generation logic. This includes cleaning up associated environment variables and removing unused dependencies like jspdf and pdfmake.

- Delete `src/app/api/printerz-proxy/route.ts` and `src/lib/pdf-generation.ts`
- Remove `/api/printerz/render` endpoint from `src/server/index.ts`
- Clean up `package.json` and `.env.example`
- Simplify `EnhancedTranscript` and `ErrorState` components by removing unnecessary lint suppressions and logic complexity
