Fix Building timeout and macbook shortcuts (#1964)

* Fixed shortcuts not working on mac

* fixed top level vertices and added timeout

* revert flowStore changes

* chore: Update worker timeout setting

* feat: Add endpoint to retrieve config settings

The commit adds a new endpoint `/config` to retrieve the configuration settings. This endpoint returns the `ConfigResponse` model, which includes the `timeout` value. The implementation handles any exceptions and logs them appropriately.

* feat: Add fetchConfig function to retrieve configuration settings

This commit adds a new function fetchConfig to the API utils module. The function makes an HTTP GET request to the /config endpoint and returns the configuration data. Any errors that occur during the request are logged and rethrown. This function will be used to initialize the application with the fetched configuration.

* revert changes

* feat: Add setupAxiosDefaults function to initialize Axios configurations

This commit adds a new function setupAxiosDefaults to the API utils module. The function fetches the configuration data using the fetchConfig function and sets up default configurations for Axios. It sets the base URL and timeout for Axios requests based on the fetched configuration. This function will be used to initialize Axios with the correct configurations.

* fix(langflow): rename 'timeout' setting to 'worker_timeout' for clarity and consistency
feat(langflow): add 'frontend_timeout' setting to control frontend API call timeout
chore(langflow): reorganize imports and constants in settings module for better readability

* Set frontend_timeout to 0
