fix: allow setting auto.offset.reset=latest on /query-stream endpoint

[vcrfxia]

Description

Not only does the /query-stream endpoint default to auto.offset.reset=earliest, it currently doesn't allow the user to specify auto.offset.reset=latest since the endpoint hardcodes putting auto.offset.reset=earliest into the properties map, which overrides any user specification for the property value.

This PR fixes the issue in a really hacky way. The solution is brittle since it requires checking for all possible aliases of the auto.offset.reset property. Ideally we'd evaluate the properties first and then apply the override but that would involve changes to the engine.

Testing done

Added an integration test.

Reviewer checklist

• Ensure docs are updated if necessary. (eg. if a user visible feature is being added or changed).
• Ensure relevant issues are linked (description should include text like "Fixes #")
