Fix routing functions to return proper structures and use NextResponse

- Update routing functions to return complete data structures (success, data, error, meta, tenant, package, entity, action, id)
- Change errorResponse and successResponse to use NextResponse.json for proper Next.js compatibility
- Make loadPackageMetadata and schema registry functions synchronous (code calls them without await)
- Reduced errors from 188 to 159
