* Report a measured zero incremental instead of erasing it

A CBT incremental with an exactly zero delta -- nothing changed since
the parent -- was reported identically to a backup that moved the whole
device. `velero backup describe --details` printed only
"Moved data Size (bytes): 3221225472" with no incremental line, and
status.incrementalBytes was absent, for a run that transferred nothing.
The best possible CBT outcome displayed as the worst, and was
indistinguishable from a genuine full, a whole-device fallback, or a
backup predating incremental accounting.

The zero was being erased twice. Besides the API status fields,
datapath.BackupResult also carried omitempty, and that struct crosses a
JSON boundary from the data mover pod to the controller (see
micro_service_watcher.go), so the value was destroyed before the
controller could persist it. Every uploader always reports a figure
there, so 0 internally always means "transferred nothing" -- dropping
omitempty is sufficient and correct for that hop.

The API fields move to *int64 rather than just dropping omitempty. The
field shipped in v1.18.0-v1.18.2, so backups exist whose stored volume
info has no incrementalSize at all; with a plain int64 those unmarshal
to 0 and would render "Incremental data Size (bytes): 0", a false claim
of a perfect incremental on a run that never measured one. nil means not
measured, a pointer to 0 means measured zero. Both fields already carry
+optional, so the generated CRD schema is unchanged and no regeneration
is required.

Display gates relax from > 0 to != nil in all three places, including
volumesByPod.Add, whose signature takes *int64 now; the restore describer
passes nil, which is correct since restores measure no incremental.

Verified live: the same zero-delta scenario that reported <none> now
reports 0 and renders "Incremental data Size (bytes): 0", while an older
backup described with the new client still correctly prints no
incremental line at all.

* Regenerate CRDs for IncrementalBytes pointer type

make update-crd was missed in the original commit. Regenerated with
the pinned controller-gen v0.16.5 to avoid unrelated version-annotation

* Address review: make IncrementalBytes a pointer to preserve backward compat

Per Lyndon-Li's review on #10309: dropping omitempty on the plain int64
field breaks compatibility with a data mover from release-1.17 or
earlier that predates IncrementalBytes and never writes the key -- the
new controller would unmarshal a zero value ("nothing transferred")
instead of recognizing the field is simply absent ("not measured").

Switch to *int64 with omitempty restored:
- an old mover's omitted key unmarshals to nil ("not measured")
- a current mover's genuine zero still serializes the key, unmarshaling
  to a non-nil pointer to 0 ("measured zero")
- nonzero values work exactly as before
- an old controller can still unmarshal a numeric value from a new mover

pkg/controller/data_upload_controller.go and pod_volume_backup_controller.go
assign the wire-struct field directly to their already-*int64,omitempty
CRD status field instead of re-wrapping it with ptr.To, since both are
now the same pointer type.

* Fix CI: update marshal-fail test assertions for IncrementalBytes pointer

Both backup_micro_service_test.go files hardcoded the %v-formatted
zero-value BackupResult struct in an error-message assertion. Now that
IncrementalBytes is *int64, its zero value prints as <nil> instead of 0.

According to comment, calling executePVAction aims to reset PV's
claimRef, but the reset logic was moved into resetVolumeBindingInfo
since release-1.4.
