feat(18-01): money list column, danger record actions, preview Edit rule and table kit (task 2)

- columns.yaml type: money with currency or currencyFrom (exactly one),
  never searchable, not sortable by default; every list row carries the
  currencyFrom column's value under its own key; the schema serves
  currency and currencyFrom on the column
- pact.AdminRecordAction.Danger, served as danger on cabana.RecordAction
  (absent when false); RecordActions.vue passes it to the confirm dialog
- CellValue money kind through formatMoney with the row's code, the em
  dash when empty and the amount alone without a code; DataTable aligns
  money headers and cells to the right
- PreviewView renders Edit only when a registered value field allows
  update (F6)
- main.css .summer-table* and .summer-stat__note kit classes (F7) over
  --c-* variables; cabana README kit rows
- fixture record actions void (danger) and resend; TestMoneyListCompile,
  TestMoneyListSmoke and TestRecordActionDangerSmoke; regenerated OpenAPI
  and TS types; rebuilt dist; lists-and-filters and admin-controllers docs
