The unified /api/connections aggregator emits IDs as {type}:{name}
(e.g. "pve:delly"), but the PUT/DELETE/refresh-cluster/test endpoints
only parsed the legacy {type}-{index} array-position form. That left
the new Connection surface unable to drive any mutation against the
entries it lists.
HandleUpdateNode, HandleDeleteNode, HandleRefreshClusterNodes, and
HandleTestNode now route the incoming ID through a shared
resolveNodeID helper: colon-form resolves by Name (404 on miss),
dash-form keeps the existing index semantics. Frontend connection
client gains setEnabled/remove that dispatch to the right per-type
endpoint by ID prefix.
