Expose remote_table option in Native Queries Relationships UI

Reading [the native queries docs ](https://hasura.io/docs/latest/schema/postgres/native-queries/#relationships-with-tables), at the part of relationships with table it shows the ability to map a table to a logical model's column via the remote_table option:

```json
{
"type": "pg_track_native_query",
"args": {
"arguments": {},
"array_relationships": [],
"code": "SELECT * FROM (VALUES (1, 'Logical Models', 1), (2, 'Native Queries', 2), (3, 'Relationships', 3), (4, 'Graph Relationships', 4), (5, 'Permissions', 5)) as t(\"id\", \"title\", \"author_id\")",
"object_relationships": [
{
"name": "author",
"using": {
"column_mapping": {
"author_id": "id"
},
"insertion_order": null,
"remote_table": "authors" <------ HERE
}
}
],
"returns": "article",
"root_field_name": "get_articles",
"source": "default",
"type": "query"
}
}
```

this option is missing on the UI


Start by reviewing the native queries documentation section on relationships with tables and the existing Native Queries Relationships UI shown in the issue. Trace how relationship options are represented and rendered, then expose the remote_table option so it can map a logical model column to a table as described. Done means the option is available in the UI and produces the documented configuration.
