tests: Enhance component testing and error handling with dynamic retrieval (#4526)

* Add module parameter to build_component_instance_for_tests function for dynamic component retrieval

* Enhance component test base with detailed version mapping and error handling

- Introduced `VersionComponentMapping` TypedDict for structured version mapping.
- Updated `FILE_NAMES_MAPPING` to use a list of `VersionComponentMapping`.
- Added comprehensive error messages for missing or invalid mappings in `test_all_versions_have_a_file_name_defined`.
- Improved `test_component_versions` with detailed exception handling and error reporting.
- Ensured `component_class` is defined before running tests.

* Refactor FILE_NAMES_MAPPING to use a list of dictionaries for better structure and readability in test_prompt_component.py

* refactor: Enhance ComponentTestBase with fixture validation and improved version handling

* Refactor test setup in `test_prompt_component.py` to use fixtures for improved modularity and readability

* fix: Add PlaceholderGraph NamedTuple and handle 'graph' attribute in Component class

* Add attribute checks for 'graph' and 'vertex' to prevent errors

* Handle missing 'graph' attribute in 'store_message' method to prevent errors.

* Handle missing 'graph' attribute in Message creation to prevent errors

* Handle missing 'graph' attribute in chat message flow ID assignment

* Add component code to test instance creation and error logging

* Update SUPPORTED_VERSIONS to remove older versions

* test: add unit tests for ChatInput and TextInputComponent

Implement comprehensive tests for both ChatInput and TextInputComponent to ensure proper functionality, including message responses and handling of various input scenarios. This enhances reliability and aids in future development.

* test: add unit tests for ChatOutput and TextOutputComponent

Implement comprehensive tests for ChatOutput and TextOutputComponent, validating message responses, source properties, and behavior with various input types to ensure reliability and consistency across output components.

* Update JSON files to improve code readability and add missing info fields

- Added missing `info` fields to various input components to provide better context and descriptions.
- Improved code readability by ensuring consistent formatting and structure across JSON files.
- Updated `message_response` method to handle cases where `graph` attribute might not be present.
- Enhanced `build_vectorize_options` method to set `authentication` and `parameters` to `None` if no values are provided.
- Refined `AgentComponent` to include `info` for `agent_llm` and other fields, improving clarity on their purpose.

* Refactor: update attribute access to use private `_vertex` attribute

* test: enhance TextInputComponent tests and update properties assertions

* Remove redundant unit tests for output components in test_output_components.py

* feat: add PlaceholderGraph for backwards compatibility and enhance Component attributes

* fix: improve run_id assignment and ensure user_id is a string in PlaceholderGraph

* Add check for non-empty incoming_edges in get_properties_from_source_component
