CHW-3402 PaddleWebhookBadEvent

paddle webhook event body could not be parsed; event_id / event_type missing

Default message: paddle webhook event body could not be parsed; event_id / event_type missing
HTTP status: 400 (client)

Problem. A Paddle webhook body parsed to JSON but was missing the event_id / event_type envelope fields. Cause. Paddle shape change, truncated body, or a spoofed payload that slipped past signature check (shouldn’t happen). Fix. Inspect the raw body; Paddle retries will re-deliver. HTTP 400.
