Fixes:
- Connection lines now start directly from the spouse line (parentY)
instead of below the parent symbols (parentY + halfSymbol), ensuring
lines connect properly without gaps
- PED export now uses metadata.label instead of internal ID, so user-
defined labels are preserved in exported files. Parent references
(fatherId, motherId) also use the label mapping for consistency.
