feat(usage): distinguish real edits and template delivery with v5 consent (#1339)

* feat(usage): distinguish real edits and template delivery with v5 consent

* fix(usage): exclude queued test messages and count reorders as edits

- queueEmail carries usageEligible: false into email_data and the queue
  processor passes it on, so the dev tools' send-test-email no longer
  records email_template_delivery once the worker sends it.
- event-types/reorder and categories/reorder-global compare the persisted
  order before and after and record the v5 edit markers only when it
  changed, matching the display_order edit already counted on PUT.
- normalized() builds arrays with Array.from so a row array from the sqlite
  binding compares equal under Jest's separate realm.

* fix(usage): cover per-gallery category order and workflow test runs

- categories/reorder records category_editing when an event's override
  changes; reorder/:eventId records it when an override was actually
  removed.
- send_email and the collections handoff pass usageEligible: false for a
  workflow test run (engine.testRun sets __test), so a non-dry test send is
  not counted as template delivery.
