Move NWB test expectations to YAML

[ishan372or]

Description

What is this PR

• Bug fix
• Addition of a new feature
• Other

Why is this PR needed?

Some NWB test expectation data was previously defined directly inside the test file (test_save_poses.py). Separating test data from test logic improves readability and maintainability, and makes it easier to modify or extend expectations without changing the test implementation.

What does this PR do?

Moves the NWB expectation dictionaries into a YAML file: tests/data/nwb_expectations.yaml and loads the test expectations in test_save_poses.py using yaml.safe_load

Does this PR require an update to the documentation?

No documentation updates are required, as this change only affects internal test organization.

Checklist:

• The code has been tested locally
• Tests have been added to cover all new functionality
• The documentation has been updated to reflect any changes
