`@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.
