Show a better output for `multisig list` command

Currently when executing the `multisig list` command, the output only displays the folders and files uploaded to S3. A better output would be a table with some details about the transactions, this could even leverage the description parameter that was added in the tool.

Start by locating the implementation of the `multisig list` command and reviewing how it currently displays folders and files uploaded to S3. Check how the existing description parameter is represented, then define the transaction details and table columns before implementing the improved output. Done means the command presents transaction information in a readable table instead of only listing S3 paths.
