[Bug]: `Target types` filter does not work on the Events page in UI

[jvstme]

Steps to reproduce

1. Open the Events page.
2. Set the Target types filter to any allowed value.

Actual behaviour

The event list is always empty.

The API returns error 429:

{"detail":[{"type":"enum","loc":["body","include_target_types",0],"msg":"Input should be 'project', 'user', 'fleet', 'instance', 'run', 'job', 'volume', 'gateway' or 'secret'","input":"Instance","ctx":{"expected":"'project', 'user', 'fleet', 'instance', 'run', 'job', 'volume', 'gateway' or 'secret'"}}]}

Expected behaviour

The event list shows all events that have at least one target of the specified type.
