CODEOWNERS: add hannes-cf to DNS and 1.1.1.1 product paths (#30875)

Adding myself as a co-owner for DNS and 1.1.1.1 product documentation
following the PCX team dissolution. Product PMs are now responsible for
docs ownership and approvals.

Paths:
- 1.1.1.1 (docs, partials, assets)
- dns (docs, dns-firewall, internal-dns, private-origins)

Existing co-owners preserved on all paths.
