Closes #557

What changed

  • fan out Web Push across devices with a configurable concurrency ceiling (default 8)
  • preserve ordered sends within each device
  • stop retrying later threads on a failed endpoint during the same poll
  • document the production setting

Verification

  • RED observed for bounded cross-device concurrency, per-device failure short-circuiting, and poll-loop configuration wiring
  • python3 -m pytest tests/test_push_notifications.py -q — 17 passed
  • python3 -m pytest tests/ -q — 1156 passed
