🔧 chore(config.yml): update Swagger API overview and paths

The Swagger API overview and paths have been updated to reflect the latest changes in the API. The changes include adding support for a new environment variable, `process.env.PORT`, to allow the application to run on a configurable port. Additionally, the Swagger API documentation has been updated to reflect the latest API version and routes.

🔍 chore(links): update links to use HTTPS instead of HTTP
The links were updated to use HTTPS instead of HTTP to improve security and prevent potential man-in-the-middle attacks.

🚨 fix(Openapi.json): fix invalid JSON syntax by removing trailing comma
The Openapi.json file had an invalid JSON syntax due to a trailing comma in the "file_path" field. This commit removes the trailing comma to fix the syntax error.

🔥 chore(test_graph.py): remove unnecessary comments and assertions
🚀 feat(test_graph.py): add file creation and deletion to test_file_tool_node_build and test_toolkit_node_build
The comments and assertions that were removed were unnecessary and did not add any value to the code. The test_file_tool_node_build and test_toolkit_node_build tests now create a file and delete it after the test is run. This ensures that the tests are self-contained and do not leave any artifacts behind.
