Secured sandbox auto signature

[sitole]

Some users report that JS/Python types lack a useSignature attribute, which only works when secure=true is set for the sandbox. This change removes the useSignatrue parameter and makes all upload/download URL requests signed if secure was provided, making sure the function will work for all possible cases.

This is also a change needed for safe migration to allow secure=true as default when creating a sandbox.

Pull Request Overview

This PR simplifies the sandbox file URL signing mechanism by automatically determining when to use signed URLs based on whether the sandbox was created with the secure option. It removes the manual useSignature parameter from both JavaScript and Python SDKs, making signed URLs the default behavior for secure sandboxes.

• Removes useSignature parameter from downloadUrl and uploadUrl methods
• Automatically enables URL signing when sandbox has an access token (secure mode)
• Updates error messages to clarify that signature expiration requires a secured sandbox
