martin brook f8a9f1f07a fix: image centering bleed (#1096) ...

## Summary

* Fixes #1026 
* Added a reproducer chapter to the epub generator for this case
* The fix is in endElement — when leaving a block/header element that
had an empty text block, reset the alignment to the user's default so it
doesn't bleed into the next sibling. This preserves accumulated margins
from parent elements while preventing stale alignment from carrying
across.
