Review Comment:
   [grok-4.6] @bobpaulin Thanks for the pointer. I extended the existing 
change-version system test so it now also changes back from Version 2 to 
Version 1.
   
   After that revert:
   - the managed Process Group id is unchanged
   - the flow name stays `Change Version Flow v1` (it is not swapped to the 
Version 2 name)
   - `Shared Property` is still `kept-across-reload`
   - Version 2's `New Property` is dropped from the stored configuration. 
Leaving it in place made the Connector invalid (`Property 'New Property' is not 
defined`), so the framework now drops properties and configuration steps that 
the current Connector version does not declare after `migrateProperties`.
   
   If a Connector does not support a given version change, it can still fail 
the swap by throwing from `migrateProperties`, `initialize`, or 
`onStepConfigured`. We did not add a separate "unsupported" flag for that.
   
   The same test then enters Troubleshooting, adds a processor, and exits. The 
extra processor is removed, the Version 1 configuration remains, and the 
Connector can be started again.
