feat: bt auth profiles --print-jwt-token

[Cedric / ViaDézo1er (viadezo1er)]

To help the gateway since it needs the token.
fix --json being ignored by bt auth subcommands.
bt auth profiles --profile name now only shows the selected profile

❯ bt auth profiles --profile ced-test-1 --json --print-jwt-token | jq
[
  {
    "name": "ced-test-1",
    "auth": "oauth",
    "org": "ced-test-1",
    "user_name": "Cédric Halber",
    "user_email": "my-email@example.com",
    "status": "ok",
    "jwt_token": ".........."
  }
]
