Auto-populate required slices in profile createResource()

[ryukzak]

Summary

• Array fields with required slices (min >= 1) are now auto-populated with discriminator match values in createResource()/create()
• Users no longer need to pass empty arrays and manually call slice setters for required slices
• Example: category on bodyweight/BP profiles is auto-set with VSCat discriminator; component on BP is auto-set with systolic/diastolic stubs

// Before: category was a required param, user had to setVscat() separately
const bp = bpProfile.create({ status: "final", category: [], subject: {...} });
bp.setVscat();

// After: category auto-populated, removed from params
const bp = bpProfile.create({ status: "final", subject: {...} });

Test plan

• Updated bodyweight tests — removed category: [] from create calls, verified auto-population
• Updated BP tests — removed category: [], verified component auto-populated with systolic/diastolic stubs
• Updated snapshots
• Regenerated R4 profile examples
• bun run typecheck && bun run lint && bun test
• make all
