feat: phone-call + sms scrapers

M4 (/pc/ CRM module): mirror phone-call + SMS endpoints.

Scraper (app/scraper/call.py):
- scrape_phone_calls: POST /pc/callLog/list -> PhoneCall (channel='phone_call')
  Envelope data.data / data.totalCount / data.pageCount; page-number pagination.
  incomingCall (1=incoming/0=outgoing) stored DIRECTLY (no inversion, unlike
  voice-call isSend); callSeconds preferred over legacy callDuration string;
  startCallTime (YYYY-MM-DD HH:MM:SS) -> ms epoch.
- scrape_sms: POST /pc/customer/smsLogsList -> Sms (channel='sms')
  Envelope data.data / data.dataCount (NOT totalCount), no pageCount;
  relies on empty-page stop signal. createTime (YYYY-MM-DD HH:MM) -> ms epoch;
  empty smsSub normalized to None content_preview.

Shared helper: extracted parse_datetime_to_ms(value, formats) to
app/scraper/parsers.py and refactored _parse_voice_start_time to delegate
(DRY across all three call/SMS datetime sources).

Repos: upsert_phone_call + upsert_sms (idempotent Core upsert by call_id /
sms_id). Added create_time to _INT_FIELDS for defensive numeric-str coercion,
matching start_call_time's existing treatment.

Orchestrator: sync_phone_calls + sync_sms (full re-scrape + idempotent upsert
+ SyncRun log + watermark), mirroring sync_wechat_voice_calls. Entity types
'phone_call' and 'sms'.

Tests (+15, suite 211 -> 226): respx-mocked scraper tests (2-page fixtures
exercising pagination + full field mapping), repo idempotency + coercion
tests, orchestrator SyncRun/watermark tests with monkeypatched scrapers.
ruff clean.
