"""Tests for the phone-call + SMS scrapers (M4, ``app/scraper/call.py``).

Drives the real page-number pagination + normalization logic through
``respx`` by wiring a real ``YunkeClient`` (primed with a fake session so the
login flow is skipped) against a mocked transport.

Two endpoint suites:

* ``POST /pc/callLog/list`` (phone calls) — envelope
  ``data.data`` / ``data.totalCount`` / ``data.pageCount``. Maps to
  :class:`PhoneCall` with ``channel="phone_call"``. ``incomingCall`` polarity
  is ``1=incoming / 0=outgoing`` and is stored DIRECTLY (no inversion — unlike
  the voice-call channel's ``isSend``).
* ``POST /pc/customer/smsLogsList`` (SMS) — envelope ``data.data`` /
  ``data.dataCount`` (note: ``dataCount``, NOT ``totalCount``), no
  ``pageCount``. Maps to :class:`Sms` with ``channel="sms"`` (the model
  default).

Both fixtures ship multiple pages so the tests exercise pagination across the
empty-page stop signal end-to-end, and assert the full field mapping incl.
the two distinct datetime string formats (``YYYY-MM-DD HH:MM:SS`` for calls,
``YYYY-MM-DD HH:MM`` for SMS) parsed to ms-epoch.
