[Dev UI] Available datasets should be scoped to the target being tested

[MichaelDoyle]

Overview

Currently, it's possible to create a "model" dataset, and try to evaluate a "flow" with that dataset. Fundamentally, these are incompatible and will cause an error.

User goal(s)

Help choosing relevant datasets.

Requirements

1. At minimum, we should scope the target under test to datasets of the same type.
2. Within the same type (particularly flows) we should consider looking for schema compatibility as well.

Acceptance Criteria

• 1 When running an evaluation, only relevant/compatible datasets are available

Designs

After choosing a flow, model datasets are still available in the drop down:

Running the evaluation shows success, but it is really a failure:
