Frontend Only Displays up to 10 Active Executions

[trRad23]

Bug Description

When the concurrency limit (N8N_CONCURRENCY_PRODUCTION_LIMIT) is set above 10 (e.g: 50), the frontend always shows a maximum of 10 active executions, even if more are running.

E.g:
The tooltip in the executions tab only displays 10 out of 50 running executions.

The tooltip shown in the image above is in the ConcurrentExecutionsHeader.vue component. It appears the running execution count is calculated based on the results from the fetchExecutions function in executions.store.ts. The fetchExecutions function seems to impose a 10 items per page limit, which results in always showing 10 as the total running executions (shown below).

To Reproduce

1. Set N8N_CONCURRENCY_PRODUCTION_LIMIT to a value greater than 10 (e.g., 50).

2. Trigger enough executions to exceed the concurrency limit (e.g., send 100 simultaneous requests if the limit is 50).

3. Go to the frontend and observe the active executions count in the tooltip.

4. The tooltip will only show 10 active executions, even though more are running.

Expected behavior

The frontend should display the actual number of active executions, reflecting the total number of running executions. The tooltip should show the correct count of active executions based on the actual running executions, rather than being capped at 10.
