MT#63508 Avoid direct Vuex state mutation in CscPageCallRecording

In CscPageCallRecording a watch function was directly
modifying the Vuex state, which is not allowed in
strict mode. This change ensures that each recording
object is cloned before modification, preventing
unintended mutations of store data.
