fix: add queue position display to template creation

[cdr-robot]

Summary

• Shows the queue position for pending template creation jobs in the UI alert
• Updates the ProvisionerStatusAlert component to accept queue position and size parameters
• Updates the BuildLogsDrawer component to pass queue information to the alert component

Test plan

When creating a template:

1. If provisioners are busy, a clear queue message will be shown instead of just a spinner
2. Message will show Position in queue information when appropriate
