fix(console): blob download args

[divagant-martian]

Description

• modifies the blob download ux to make it clear, and properly enforce having either a ticket or arguments for a download
• All arguments apply to both ticket and hash but with different constrains. In the case of the ticket options can be used to override/remove ticket parts
• makes sure failures still report the help text
