feat: add blocked domains metric and expand limits (#59)

* feat: add blocked domains metric and expand limits

- Introduce `dns_top_blocked_domains` to track frequently filtered
  hostnames.
- Move `TopDomains` incrementing after the blocklist check to ensure
  it only reflects permitted traffic.
- Increase `TOP_K` from 20 to 50 for enhanced visibility across
  clients and domains.

```mermaid
graph TD
    Q[DNS Question] --> B{Blocked?}
    B -- Yes --> BD[TopBlockedDomains]
    B -- No --> AD[TopDomains]
    AD --> C[Forward/Cache]
```

* refactor: deduplicate SpaceSaver stats collection

Extracts the closure logic for gathering Top-N statistics into a
reusable helper function `newSpaceSaverStatsCallback`.

- Reduces boilerplate in `dns_metrics.go`.
- Improves maintainability by centralizing the `SpaceSaver` to map
  conversion logic.
- Adds an initial capacity hint to the results map.
