Closes: #11812 Changes: - Renamed the `hostStatusWebhookEnabled` attribute of the `HistoricalUsageSnapshot` model to `hostsStatusWebHookEnabled` and updated the definition to use the existing database column name. - Updated the inputs of the `receive-usage-analytics` webhook to accept a `hostsStatusWebHookEnabled` input. - Updated the usage statistics documentation to have the [correct variable name](https://github.com/fleetdm/fleet/blob/36e12d02e3c4e9dc741a7d5828ac74136f1f404d/server/fleet/statistics.go#L21).
