## Problem
The build is failing because the HTTP server is trying to access DNSSEC-related fields (`DNSSECQueries`, `DNSSECSuccess`, `DNSSECFailed`, `DNSSECEnabled`) from the `dns.Stats` struct, but these fields don't exist in the struct definition.

## Solution
Add the missing DNSSEC-related fields to the `Stats` struct in `dns/server.go` and ensure they're properly initialized and updated.

## Implementation Steps
1. **Add DNSSEC fields to Stats struct** in `/root/dns/dns/server.go`:
   - Add `DNSSECQueries int64` field
   - Add `DNSSECSuccess int64` field  
   - Add `DNSSECFailed int64` field
   - Add `DNSSECEnabled bool` field

2. **Initialize DNSSEC fields in NewServer** function:
   - Set `DNSSECEnabled` based on config.EnableDNSSEC
   - Initialize other DNSSEC fields to 0

3. **Update DNSSEC stats in query handling**:
   - Increment `DNSSECQueries` when a DNSSEC query is processed
   - Update `DNSSECSuccess` and `DNSSECFailed` based on DNSSEC validation results

4. **Test the fix** by running `go build` to ensure all errors are resolved

## Expected Outcome
The build will succeed and the HTTP server will be able to access the DNSSEC-related stats fields.
