Fix dynamic macro system test failures

- Fix RxJS observable setup by storing Subjects directly in port Maps
- Fix port naming consistency between DynamicMacroManager and ReactiveConnectionManager
- Add comprehensive port setup for all expected port names (default, input, output, value)
- Resolve 'sourceOutput.pipe is not a function' and 'Target port not found' errors
