fix: rename customID to customTitle in mol bond for consistency (bd-e7ou)

The --as flag description correctly says "Custom title" but the variable
was named customID and dry-run output said "Custom ID". Fixed for consistency:

- Renamed variable customID -> customTitle
- Changed dry-run output from "Custom ID" to "Custom title"

Closes bd-e7ou
