@list Order Preservation is Broken on server / Nexus

[Jackamus29]

Describe the bug
When inserting a list of values using the @container type of @list, I expect to get back the same order of values in query results.

To Reproduce

1. Create ledger

{
  "ledger": "list-order-test",
  "@context": {
    "ex": "http://example.org/ns/",
    "ex:age": {
      "@container": "@list"
    }
  },
  "insert": [
    {
      "@id": "zeti",
      "ex:age": [97, 19, 97, 19, 97]
    }
  ]
}

2. Query

{
  "from": "list-order-test",
  "@context": {
    "ex": "http://example.org/ns/",
    "ex:age": {
      "@container": "@list"
    }
  },
  "selectDistinct": { "?s": ["*"] },
  "where": {
    "@id": "?s",
    "ex:age": "?age"
  }
}

Expected result

[
  {
    "@id": "zeti",
    "ex:age": [
      97,
      19,
      97,
      19,
      97
    ]
  }
]

Actual result

[
  {
    "@id": "zeti",
    "ex:age": [
      19,
      19,
      97,
      97,
      97
    ]
  }
]

@Jackamus29 & I confirmed that even the exact test in db (https://github.com/fluree/db/blob/1507c85ab3490c4419a65e236183317a2b43196b/test/fluree/db/query/json_ld_basic_test.clj#L131-L149) when issued via server does not preserve order in query results.
