Update ni.protobuf.types dependency and corresponding code changes

[dixonjoel]

What does this Pull Request accomplish?

AB#3877568

Bubbling up changes from ni.protobuf.types to datastore-python.

Why should this Pull Request be merged?

This brings in changes from ni.protobuf.types. Prior to this, I published a new version of that package to be consumed here.

What testing has been done?

I did this in stages, i.e. make the expected code changes, see that there were several failing tests (11) with the change. Then I updated the ni.protobuf.types version and make more changes to the expected waveforms in several tests until they passed locally.

Pull request overview

This PR updates the ni-protobuf-types dependency to a newer prerelease and updates datastore-python code/tests to match the updated nitypes/protobuf waveform shapes (notably timing/scale metadata expectations).

Changes:

• Bump ni-protobuf-types to >=1.2.0dev1 (prerelease) and refresh poetry.lock accordingly.
• Update multiple acceptance tests to construct expected waveforms with explicit Timing(...) (and NoneScaleMode() where applicable).
• Adjust gRPC conversion logic to pass iterables directly into nitypes.Vector(...) rather than materializing into lists.

I'll defer to Hunter on the _grpc_conversion changes. The test changes look good to me, though.
