refactor(cli): unify ado get handling for all resources

[AlessandroPomponio]

Summary

This pull request refactors the ado get command handlers across all resource types to use a unified handle_ado_get() function. The changes consolidate duplicated output formatting logic, improve code maintainability, and provide a consistent interface for handling different output formats (TABLE, NAME, YAML, JSON, CONFIG, RAW).

Resolves #848

Files Changed

📄 orchestrator/cli/resources/actuator/get.py

Refactored to use the unified handle_ado_get() handler instead of custom table rendering logic. Removed manual NAME format handling and imports for rich.box, dataframe_to_rich_table, and ADO_INFO_EMPTY_DATAFRAME.

📄 orchestrator/cli/resources/actuator_configuration/get.py

Simplified to use a single handle_ado_get() call instead of branching between handle_ado_get_default_format() and handle_ado_get_special_formats(). Removed conditional logic for different output formats.

📄 orchestrator/cli/resources/context/get.py

Refactored to use handle_ado_get() for both NAME and TABLE formats (using DataFrame), and for structured formats (YAML, JSON, CONFIG) using resources. Removed manual table rendering and custom formatting logic.

📄 orchestrator/cli/resources/data_container/get.py

Simplified to a single handle_ado_get() call, removing the conditional logic that branched between TABLE and other output formats. Cleaned up imports.

📄 orchestrator/cli/resources/discovery_space/get.py

Refactored all three code paths (matching_point, matching_space, and standard) to use handle_ado_get(). Removed manual table rendering with dataframe_to_rich_table() and custom format handling. Removed unused imports.

📄 orchestrator/cli/resources/experiment/get.py

Replaced manual table rendering logic with handle_ado_get() call. Moved empty DataFrame check inside the sort operation to handle it more gracefully. Removed imports for rich.box, dataframe_to_rich_table, and ADO_INFO_EMPTY_DATAFRAME.

📄 orchestrator/cli/resources/measurement_request/get.py

Simplified to use handle_ado_get() for rendering measurement request resources. Removed manual formatting with format_resource_for_ado_get_custom_format() and the "getting output ready" spinner.

📄 orchestrator/cli/resources/operation/get.py

Simplified to a single handle_ado_get() call, removing conditional branching between TABLE and other formats. Cleaned up imports.

📄 orchestrator/cli/resources/operator/get.py

Refactored to use handle_ado_get() with DataFrame, removing manual NAME format handling and table rendering logic. Removed imports for rich.box and dataframe_to_rich_table.

📄 orchestrator/cli/resources/sample_store/get.py

Simplified to a single handle_ado_get() call, removing conditional logic for different output formats. Cleaned up imports.

📄 orchestrator/cli/utils/resources/handlers.py

Major refactoring that introduces the unified handle_ado_get() function and format-specific handlers (_handle_name_format(), _handle_table_format(), _handle_raw_format(), _handle_structured_formats()). This consolidates logic from the removed handle_ado_get_default_format() and handle_ado_get_special_formats() functions, providing a single entry point that delegates to efficient, format-specific implementations. Added helper function _write_or_print_output() for consistent output handling.
