Goal:

Based on the reviews [1] [2], we identified several issues in the validation webhook that can be addressed to enhance how we determine the validity of a TopologyRef.

Although these reviews are part of the nova-operator, improving the validation webhook will require updates across the board, and stories will be added for each operator.

With this update we expect that TopologyRef basePath is not resolved as part of the helper, but should be in the same code as the struct field referencing it.
The webhook related envTests should give evidence of the path in the error message [4].
