Add confirmed family members and reverse DNS details to relay dialog

[center2055]

Fixes #26.

Summary

• return enriched relay details with confirmed family members and verified/unverified reverse-DNS host names
• add backend lookup and caching for reverse-DNS results
• render the new relay dialog sections and add an explicit action to show the confirmed family on the map

Verification

• ./gradlew.bat test --tests org.tormap.service.ReverseDnsLookupServiceTest --tests org.tormap.service.RelayDetailsQueryServiceTest
• corepack yarn install --immutable
• corepack yarn build
• corepack yarn lint

Notes

• The full backend Spring test suite still depends on Docker/Testcontainers; it was not runnable in this environment without Docker.
