Enrichment matrix fixture

A curated table carrying one column of each authored kind — identifier, numeric, categorical, annotated-numeric, and free text — so the e2e matrix can assert each enrichment lands on the columns it should and shows a disabled lozenge on the ones it should not. This is the fixture that catches the issue #48 mis-typing class (identifiers summed as numbers; annotated numeric cells losing sort/filter). It offers the full registry set (enrichments: []) with the toggle panel shown.
