/// Run interactive mode to collect secret information from user

/// # Returns
///
/// Returns a `SecretRequest` with all user-provided information,
/// or an error if the user cancels (Ctrl+C) or provides invalid input.
///
/// # Errors
///
/// Returns error if:
/// - User cancels with Ctrl+C
/// - Input validation fails
/// - I/O error occurs during prompting
