/**
 * Composable for merging, normalizing and enhancing table headers.
 *
 * @param headersProp - Headers provided by the table props.
 * @param storedHeaders - Optional headers restored from table state persistence. When both
 *   sources are defined, persisted headers provide the base order and prop values override
 *   matching headers. This value is not reactive because persistence is initialized once.
 * @param filterInputConfig - Optional filter-input configuration indexed by column key.
 * @returns Reactive header collections and utilities for retrieving or enhancing headers.
