/**
 * Ported from legacy henza_admin/src/components/x-table/model/{XTbl,Xtc}.js
 * and src/table/index.js (ColCreator).
 *
 * The fluent column API is preserved exactly — `new Xtc(key, title).filterText()
 * .renderSlot('x').noSort()` builds the same shape the legacy table schemas used,
 * so the 18 schema files port over with only their import path changed.
 *
 * Legacy had FOUR near-duplicate XTable forks (x-table/, x-table_select/,
 * custom-xtable-select/, backup-table/, ~1,300 LOC). Per the agreed decision this
 * port keeps ONE — the x-table/ variant, which is the most complete (it is the
 * only one with QuerySelectTableFilter).
