* feat: allow components to be passed in set method
* fix: Add test for graph set method with valid component
* set value variable to the output callable
* refactor: Update test_component.py to use set_component method
This commit refactors the test_component.py file in the custom_component directory. The test_set_invalid_input() function has been renamed to test_set_component() to better reflect its purpose. Additionally, the test_set_component() function now sets the agent parameter using the set_component() method instead of raising a ValueError. This change improves the readability and maintainability of the code.
* refactor: Fix formatting issue in _build_error_string_from_matching_pairs
The _build_error_string_from_matching_pairs method in the Component class had a formatting issue when input types were empty. This commit fixes the issue by adding a check for empty input types and providing an empty list as a fallback. This improves the accuracy and readability of the error string generated by the method.

* Commit to solve Model not loading issue
The issue was that the url of the models: api/tags was not parsed correctly.
It was having a // hence used urlencode to parse it properly.
Th e correct apporach works only if the base_url is correct,i.e a valid ollama URL:
for DS LF this must be a public ollama Server URL.
* updated the component Ollama Component
changed the get model to take in base url and the function will make the expected url for the model names. This makes the function better, than providing the model url as paramter.
Added Pytest, 7 tests, 1 test excluded for future implememtstion: test_build_model_failure
Make lint and Make format had touched multiple files
* removed unwanted print statements
removed unwanted print statements.
make format, formatted a lot of .tsx files also

* refactor: update schema.py to include Edge related typres
The `schema.py` file in the `src/backend/base/langflow/graph/edge` directory has been updated to include the `TargetHandle` and `SourceHandle` models. These models define the structure and attributes of the target and source handles used in the edge data. This change improves the clarity and consistency of the codebase.
* refactor: update BaseInputMixin to handle invalid field types gracefully
The `BaseInputMixin` class in `input_mixin.py` has been updated to handle invalid field types gracefully. Instead of raising an exception, it now returns `FieldTypes.OTHER` for any invalid field type. This change improves the robustness and reliability of the codebase.
* refactor: update file_types field alias in FileMixin
The `file_types` field in the `FileMixin` class of `input_mixin.py` has been updated to use the `alias` parameter instead of `serialization_alias`. This change ensures consistency and improves the clarity of the codebase.

* refactor: add _template_config property to BaseComponent
Add a new `_template_config` property to the `BaseComponent` class in `base_component.py`. This property is used to store the template configuration for the custom component. If the `_template_config` property is empty, it is populated by calling the `build_template_config` method. This change improves the efficiency of accessing the template configuration and ensures that it is only built when needed.
* refactor: add type checking for Output types in add_types method
Improve type checking in the `add_types` method of the `Output` class in `base.py`. Check if the `type_` already exists in the `types` list before adding it. This change ensures that duplicate types are not added to the list.
* update starter projects

* refactor: update test_inputs.py to include comprehensive unit tests for input classes
Add comprehensive unit tests for the input classes in the test_inputs.py file. This change ensures that the input classes are thoroughly tested and functioning correctly. The unit tests cover various scenarios and edge cases to validate the behavior of the input classes. This improvement enhances the reliability and stability of the codebase.
* refactor: remove invalid input tests for DataInput and FileInput in test_inputs.py
Cleaned up unnecessary test cases for invalid input types
* refactor: improve validation for IntInput and FloatInput value types
* refactor: add async version of get_file_content_dicts method in Message class
