console: IPv6 addresses are labeled as DNS A records

[sweetcornna]

What happened

The console DNS guides hard-code record type A while selecting an address from a probe array that combines IPv4 and IPv6 values without preserving their family.

Reproduction:

1. Return only 2001:db8::10 in an ingress probe's dnsAddresses.
2. Open the bind-domain dialog.
3. Open the sandbox wildcard-domain dialog.
4. Inspect the displayed record type and value.

Expected: An IPv6 address should be labeled as an AAAA record, or the guide should select an available IPv4 address for an A record.

Actual: Both dialogs display record type A with value 2001:db8::10; Node classifies that value as valid IPv6/AAAA and invalid for A.

Impact: IPv6-only operators receive an invalid copyable DNS instruction and may be unable to complete domain setup.

Not applicable — the finding was reproduced from ingress-probe data through the console DNS guides and does not depend on host readiness. dor doctor was not run.

Environment

• Reproduction mode: Focused-source reproduction
• Dormice commit: 4417ae14938273f5d937c476cf7cdc57e22e53a5
• Verification: Verified in the current console and schemas at 4417ae14938273f5d937c476cf7cdc57e22e53a5; Node classified the value as IPv6 and invalid for A records.

The closed PR #101 had these notes on this. Moving them here so they are not lost, as asked.

• Fix approach: added dnsRecordType(ip) in packages/console/src/features/ingress/lib/publicIp.ts. It just check for a colon in the string, every IPv6 textual form has one and no IPv4 dotted-quad does.
• Both dialogs, BindDomainDialog.tsx and SandboxDomainCard.tsx, now call dnsRecordType(publicIp) instead of a hard-coded 'A', falling back to 'A' only when there is no public IP yet (placeholder state, same as before).
• Verification: new publicIp.test.ts with three cases, a plain IPv4 address, a compressed IPv6 address, and a full-form IPv6 address.
