WNS (Windows/Edge push) has required an X-WNS-Cache-Policy header
since April 2024; the production venv was likely still on the old
pywebpush 2.0.x installed when the app was first deployed, which
predates the library's fix. Floored the dependency at 2.4.0 (current
latest) so the next deploy picks it up.
Also logs response body and headers on any non-410/404 push failure,
not just body text -- WNS's own 400s carry their actual reason in a
header, which the old body-only logging would still have missed.
