✨ feat(chat.py): add status field to flow_data_store to track build status of flows

Browse source 
The import statement for the BuildStatus enum in the schemas module has been updated to ensure the correct import. Additionally, a new "status" field has been added to the flow_data_store dictionary to track the build status of flows. The status is set to BuildStatus.IN_PROGRESS when a flow is being built, BuildStatus.SUCCESS when the build is successful, and BuildStatus.FAILURE when there is an error during the build process. This allows for better tracking and management of flow builds.
🐛 fix(chat.py): change import statement for BuildStatus in schemas module
