feat(sdk): add global seq numbering and visibleWhen for SDK flow navigation

Fix interleaved step ordering by introducing global sequence numbers (100-4700)
instead of package-relative order. Add conditional visibility (visibleWhen) for
optional steps like Import and DSFA. Fix TOM/workflow prerequisite bugs.
