fix: remove @sofa/core and @sofa/api deps from public-api to fix Vercel runtime compatibility

- Drop `@sofa/core` and `@sofa/api` from `apps/public-api` — importing workspace packages with DB/Node dependencies broke the Vercel edge runtime
- `fetchUserData` on Trakt and Simkl importers now returns raw `unknown` API responses; parsing is deferred to the self-hosted server
- Add `source` + `rawPayload` fields to `ParsePayloadInput`; `parsePayload` procedure now dispatches to `parseTraktPayload`/`parseSimklPayload` and returns full warnings + diagnostics
- Export `ProviderEnum` from `apps/public-api/src/importers/index.ts` instead of defining it inline in `app.ts`
