Retrieves a single task template by its unique identifier. Task templates are reusable task definitions
that serve as blueprints for creating standardized tasks across programs and workflows. Use this endpoint
to fetch template details including all properties, custom fields, and configuration that can be used to
create new tasks or display template information in UI components.

Key Features:

• Retrieve complete task template definition including all properties and metadata
• Access template configuration for task creation workflows and automation
• View template structure including custom properties, default values, and field configurations
• Validate template existence before using it to create new tasks
• Display template details in template management interfaces
• Check template properties to ensure compatibility with current workflows

Authorization Logic:

1. User must have a valid JWT token with viewing or management scopes
2. User must have permission to view task templates in the space

Usage Example:

Retrieve a task template to populate a task creation form with default values, or fetch template details to display available templates in a template library. For example, GET a "Product Launch Task" template to see its default assignee, priority level, estimated duration, and custom property definitions before creating tasks from it. Use when building task creation UI or validating template configurations.
