Fixes: #1244
Depends on cryostatio/cryostat#342 (targetIds filter is added here)

Description of the change:

Updates GraphQL queries that act upon particular targets to do so by their IDs, rather than using the connectUrl as the node name filter.

Motivation for the change:

It is not guaranteed, and is not true for Cryostat Agent instances, that the discovery nodes' names are equal to their connection URLs. This fixes queries being unable to locate such nodes.

How to manually test:

1. Combine with feat(agent): enable Agent HTTP communications cryostat#342
2. Select quarkus-test-agent target
3. Go to Recordings, create a new recording, wait a few moments, then archive it
4. Click the Archived recordings tab. The recording should appear in the table
