[Fix] (Pipe): refuse an eighth sticky row at compile time - the forwarded count equals the generated sticky count

Browse Source 
- kMGPipeForwardedFieldCount = 7 was a hand-written twin of the generated kMGPipeInputStickyFieldCount, tied only by PipeCatalogue.StickyFieldsAreExactlyTheSeven; a static_assert in the header makes a PipeFields.def sticky row without a forwarder a build error instead of a test failure.
