ESQL: Change queries ID to be the same as the async (#127472)

This PR changes the list and query API for ESQL, such that the ID now follows the same format as async query IDs. This is saved as part of the task status. For async queries, this is easy, but for sync queries, this is slightly more complicated, since when creating them, we don't have access to a node ID. So instead, the status itself is just the doc ID portion of the async execution ID, which is used for salting, since this part needs to be consistent, so that when we list the queries, we can compute the async execution ID correctly.

Also, I've removed the individual ID, node, and data node tags, as mentioned in the ticket.

In addition, I've changed the accept and content-type to be JSON for lists.

Resolves #127187
