fix: passing correct httpClient, do not use DefaultClients (#3319)

most of our deployments use custom certificates, using DefaultClient
makes it virtually impossible to make share URL feature work.

this PR fixes this behavior in the implementation.

Bonus: re-use transports inside console, will add more changes to
take custom transport inputs in subsequent PR.
