refactor(platform): rename IXP _transport.py to _base_service.py

Match the platform's file-naming convention: every service module is
`_<name>_service.py`, and the shared HTTP base is `common/_base_service.py`
(class BaseService). This module plays the same role one level down — the
base service every IXP design-time service extends — so name it
`_base_service.py` (class IxpDesigntimeService is unchanged). Renames the
matching test file and drops the "transport" framing from the docstrings.
No behavior change.
