UI generates excessive GET `task/.../context` requests

[DavidePrincipi]

The UI issues a large number of GET task/.../context requests while an action is running. The problem is visible with any action that emits progress events.

Steps to reproduce

1. Create a custom action that emits frequent progress updates:

    mkdir /var/lib/nethserver/cluster/actions/progress-bug
    cat > /var/lib/nethserver/cluster/actions/progress-bug/10genprog <<'EOF'
    #!/bin/bash
    for i in $(seq 0 100); do
        echo set-progress $i >&3
        sleep 0.2
    done
    EOF
    chmod +x /var/lib/nethserver/cluster/actions/progress-bug/10genprog
   

2. Run the action:

    api-cli run progress-bug
   

3. Observe the browser DevTools: the UI generates a storm of GET task/.../context requests during the progress loop.

Expected behavior

The UI should not issue excessive polling requests for task context updates.

Actual behavior

The UI continuously sends GET requests for the task context, causing unnecessary load during actions that emit many progress events.
