Implement RFID tag dump PWA with REST API, auth, and CI

Add Next.js app with SQLite/Drizzle storage for sites and LF/HF tag
dumps, multi-user Auth.js (credentials + optional OIDC), personal API
tokens in Settings, versioned /api/v1 for UI and future CLI use,
MCT/Proxmark/JSON import-export, PWA offline shell, Vitest tests, and
GitHub Actions CI.
