inputs and data views keyed: search, select, tabs, state blocks, data table

The DataTable's pagination carries the only interpolated strings in this area
('Showing page {{current}} of {{total}}', '{{size}} / page'). No plural forms:
nothing here is a count-varying noun, so inventing one would only add a key
nobody uses.

DataTable.test.tsx now renders inside an I18nProvider with the real en-GB
catalog, so it still asserts the English a user sees rather than a dot-path.

Left/right utilities became logical (ms-/me-/ps-/pe-/start-) per D3.
