fix: Modify config.py to support pip installed apps

This commit modifies the `config.py` file in the `gull_api` module to support applications installed via pip:

- Replaces the default `load_dotenv()` call with specifying a path to the `.env` file in the current working directory.
- This enables environment variable loading for applications installed through pip which may not have the `.env` file in the module's directory.

This fix ensures that configuration handling is compatible with both local and pip installed instances of the application.
