Bug: Query cancel button doesn't stop query when clicked immediately after run

[coderabbitai]

Bug Description

When a user clicks "Run" to start a Presto query and then immediately clicks "Cancel", the query doesn't actually stop executing.

Root Cause Hypothesis

This might be because Presto's cancel route returns success even if queries aren't submitted yet to the Presto engine.

Reproduction Steps

1. Navigate to the search interface
2. Enter a query
3. Click "Run" button
4. Immediately click "Cancel" button
5. Observe that the query continues to execute instead of being cancelled

Expected Behavior

The query should be cancelled and stop executing when the Cancel button is clicked.

Additional Context

• This bug is unrelated to PR fix(webui): Log Presto cancel route output as object instead of string. #1191 which only addresses logging format in the cancel route
• May be automatically resolved in a future PR when query status is handled correctly on the client side
• Consideration needed for RESTful API design, especially for users accessing the API directly
