With no decoder injected, the webhook decodes the admitted object with
encoding/json, which turns every number into float64, so an int64
above 2^53 comes back rounded. jsonpatch up to v2.4 compared both
sides as float64 and hid this; from v2.5 it compares json.Number, and
the webhook would emit a replace that silently rewrites such a field.
Decode with apimachinery's json, which keeps integers as int64, and
pin that the patch touches only the lineage labels and scheduling.
