test(18.1-06): taglist and flat reorder unit matrices, partitioned flat smoke and admin specs (task 2)

- TestTaglistFieldValidate: both modes, trim, dedupe, empty, null, wrong shapes,
  customTags false, required; TestTaglistFieldHydrate: stored NULL and bad text as []
- TestReorderFlatNodes: parent 422, duplicate and zero id 422, missing or extra 409,
  no depth or cycle check; TestReorderFlatCompile checks the localized list schema
- TestReorderFlatSmoke/partitioned: flat reorder within one partition on Postgres
- vitest: script markup as text, Backspace, blur, paste, datalist, customTags,
  string mode; flat ArrowUp/ArrowDown and the before/after drop zones
- export_test.go wrappers for the taglist save check, hydration and node check
- check-phase18.1.sh requires the new names in the go, admin and postgres stages
