domain: lower the username resolvability floor to 3

Browse source 
MinCollectibleUsernameLength doubles as the resolve-time floor for every
username kind (contacts.resolveUsername, the public web landing page),
not just collectible minting. It was still 4 after the admin write path
was lowered to 3, so an operator-assigned 3-character username could be
set but never actually resolved by anyone. Match the two floors.
