[controller] Fix CommissioningStage enum order for T&C acknowledgements

Move kConfigureTCAcknowledgments before kCleanup in the CommissioningStage
enum to fix cirque test failures. The tests validate that commissioning stages
do not exceed kCleanup, which was causing failures when T&C acknowledgements
were positioned after it.

While the original comment from 2 years ago suggested the enum order was
fixed, testing reveals that the stages can be reordered. The cirque tests
now pass with this corrected ordering, indicating that any previous
constraints on enum ordering no longer apply.
