Why does ModSecurity block my webhooks on JSON keys?

This is expected for data types with large time-series sample arrays (heart rate, SpO2, and similar), where a full day easily exceeds 1000 JSON keys.

The payload follows the documented schema and is already a single data payload for one user and one type, so there is nothing to split further.

Fix it on the ModSecurity side:

• Raise SecArgumentsLimit for the endpoint, or

• Add a rule exclusion so the JSON-keys rule does not apply to incoming Terra payloads.
