Add entangler errors to median data #5364

Adds theta and phi entangling angles to published median data.

These weren't part of the exposed QCS metrics when this calibration was run, but we were able to reconstruct them from historical data stored internally. The latest QCS calibration metrics report these by default.

Thanks especially to @dkafri for the tools necessary to extract this data - once I found the matching dataset it was pretty much a one-click process.

Does it make sense for there to be a test to check that all the expected types of data are present?

Glad it was helpfu!

Done. Also tacked on a value-check for Weber to ensure we have the right dataset.

This PR adds Z phase angles for sqrt-ISWAP gates and tools for accessing them. Follow-up to #5364.

Z phase angles are captured in a different calibration process than the other error metrics, and thus require a slightly different pipeline to access them. Key points to note about this data:
- This only includes zeta and gamma, as theta and phi already appear in the QCS metrics and chi is not currently captured by any calibration process we use.
- Qubit (6, 1) was in a bad state when the Weber data was taken, and thus has no Z phase angles in the sample data. The pipeline will treat this as zeta=gamma=0 for gates touching this qubit.
