List public user connections

Returns a user's linked-account connections. Access requires a public profile or self: a non-self viewer of a limited or private profile gets 403, which is stricter than the stats, teams, and organizations endpoints that also allow limited profiles. Non-self responses include only the connections the user marked visible on their profile; self responses include all of them. isVerified is true when the connection's platform matches one of the user's linked OAuth providers, not the connection's self-reported flag. Not paginated: returns the full matching set as connections plus a count, in no guaranteed order. Banned users return 404. Requires users.profile:read.
