Remove unused scope Packages::Npm::Metadatum.package_id_in

Summary

Removes the unused scope Packages::Npm::Metadatum.package_id_in from app/models/packages/npm/metadatum.rb.

scope :package_id_in, ->(package_ids) { where(package_id: package_ids) }

Verification

This scope was verified as unused by:

• keela --type scopes flagged it as unused (live report + scripts/lint/keela_baseline.yml)
• Grep search found no callers (app/, lib/, ee/, config, views, GraphQL)
• Not used in scope chaining
• Not used in merge() calls
• Not used as default_scope or association scope
• No symbol/string references (:package_id_in, 'package_id_in') or dynamic dispatch (send, public_send, try)

Cascade Removals

None - this was a standalone removal. It is a simple leaf where scope; removing it left no other code dead.
