fix(public_dns): index loop keys with item['key'] not item.key

item.values resolved to the dict's built-in .values() METHOD, not the 'values'
key, so gandi_livedns received '<built-in method values of dict object at 0x..>'
as the TXT value — garbage AND non-idempotent (the address changes each run).
Bracket-index all loop fields. Caught only by the live apply (apply=false Molecule
+ data-only pytest both missed it).
