Wrong timestamp of Input

[tuler]

🙂 Expected behavior

Input.timestamp in the GraphQL server should be number of seconds since epoch.

🫠 Actual behavior

The value is being divided by 1000 by assuming the value that comes from the blockchain was in milliseconds, when in fact it's in seconds.

🧪 Minimal test case

Query the server at
https://0x9f12d4365806fc000d6555acb85c5371b464e506.sepolia.rollups.staging.cartesi.io/graphql

{
  inputs {
    edges {
      node {
        timestamp
      }
    }
  }
}

🌎 Environment

Rollups 1.0.0

✔️ Possible solutions

Fix by assuming the value is in seconds while converting to the NaiveDateTime data type.
Or even better, remove completely the NaiveDateTime data type and leave the original i64 type.
Do we need a NaiveDateTime to do any date handling?

I confirmed that this was introduced in 0.9 when we refactored the indexer.
