Make CalciteReplaceCommandIT column-order-agnostic for analytics-engine route

The analytics-engine route and the v2 / Lucene path return columns in different
orders when there is no explicit `| fields ...` clause: parquet preserves the
storage order chosen by the on-disk format, while the Lucene path preserves
`_source` iteration order. Both are valid given the contract `verifySchema`
declares (set equality on column names), so positional `verifyDataRows`
assertions over-constrain the test and fail under
`-Dtests.analytics.force_routing=true` even when the data is correct.

Apply the same column-name-keyed match pattern Kai introduced for
`CalcitePPLRenameIT` in 59c728b (opensearch-project#5413):

  * Add `rowOf(key1, val1, ...)` to build column-keyed expected rows.
  * Add `verifyDataRowsByColumn(...)` to look up each cell value by column
    name and reorder to match the response schema before delegating to the
    existing positional `verifyDataRows` matcher.
  * Convert the four order-sensitive tests
    (`testMultipleReplace`, `testEmptyStringReplacement`,
    `testMultipleFieldsInClause`, `testMultiplePairsInSingleCommand`) to
    the new helpers.
  * Make `testReplaceNonExistentField` order-agnostic on the
    `input fields are: [...]` field list — assert that the prefix and every
    expected field name appear in the message, but not in a fixed order.

Test results against analytics-engine route via
`-Dtests.analytics.{force_routing,parquet_indices}=true`: 21/21 pass in both
the direct `CalciteReplaceCommandIT` suite and the `CalciteNoPushdownIT >
CalciteReplaceCommandIT` re-run. v2 path remains green.

Companion to the OpenSearch PR onboarding PPL `replace` command +
`replace()` / `regexp_replace()` functions on the analytics-engine route
via DataFusion `replace` / `regexp_replace` UDFs.
