panw_cortex_xdr: don't update fleet health status to degraded when template evaluation fails (elastic#17120)

The data-collection code no longer fetches the first page twice; the fix is to
add 1 in `.last_response.page` and then multiply by 100. These changes
improve the system test and add `assert.hit_count`

This change bumps minimum Kibana version to ^8.19.4 || ~9.0.7 || ^9.1.4 and adds
`do_not_log_failure: true` in set processors to avoid updating
fleet health status to degraded.
