Razvan Dimescu 231adc523d fix: NS cache lookup from authorities, UDP re-probe, shield alignment ...

- find_closest_ns checks authorities (not just answers) for NS records,
  fixing TLD priming cache misses that caused redundant root queries
- Periodic UDP re-probe every 5min when disabled — re-enables UDP
  after switching from a restrictive network to an open one
- Dashboard DNSSEC shield uses fixed-width container for alignment
- Blog post: tuck key-tag into trust anchor paragraph
