perf+fix: SAVEPOINT-per-item pollers, batched GPS inserts, parallel detail fetch

Audit fixes across the ingestion stack:

Observability
- Move log_ingestion out of batch loops in poll_alarms and poll_parking
  (was emitting N cumulative log rows per run instead of one).
- Add missing log_ingestion + t0 to poll_trips.
- Count inserted via cur.rowcount instead of naive +=1 so ON CONFLICT
  DO NOTHING no longer inflates the metric.

Resilience
- SAVEPOINT-per-item added to poll_alarms, poll_live_positions,
  poll_trips, poll_parking so one bad row no longer aborts the batch
  (webhook handlers already had this; pollers were inconsistent).

Performance
- /pushgps and poll_track_list now use psycopg2.extras.execute_values
  with ON CONFLICT DO NOTHING — 10-50x write throughput on larger
  batches.
- sync_devices and sync_driver_audit fetch jimi.track.device.detail
  concurrently via ThreadPoolExecutor(max_workers=8), cutting the
  daily registry sync from ~24s to ~3s for an 80-device fleet.
- poll_track_list split into two phases: parallel API fetch (4 workers,
  no DB connection held) then one batched write. Previously the DB
  connection was held across every per-IMEI HTTP call, risking pool
  starvation.

Security
- _validate_token uses hmac.compare_digest for constant-time token
  comparison (closes timing side-channel).
- _parse_data_list caps incoming items at WEBHOOK_MAX_ITEMS (default
  5000) so a pathological push cannot blow memory.

Tests
- Fix test_null_alarm_type_skipped: its INSERT-count assertion was
  catching the ingestion_log insert written by log_ingestion. Filter
  that out so the test checks only data-table inserts.
- Full suite: 66 passed.
