This commit introduces a new PUT endpoint `/api/v1/config/normalsub/edit_subpath`
to allow modification of the NormalSub service's subpath.
- Added `EditSubPathInputBody` Pydantic model for request validation.
- Implemented the API endpoint in `normalsub.py` router, calling the
corresponding `cli_api.edit_normalsub_subpath` function.
- Includes error handling for validation and general exceptions.
