Guest alerts are keyed by node-scoped resource IDs, and only metric
threshold alerts were re-homed after a live migration. Lifecycle alerts
(powered-state and future guest kinds) stayed keyed to the old node
forever because their resolvers only look up the new-node key, node
existence GC never fires while the source node is still online, and
nothing else consumes the move.
Generalize the migration helper to match lifecycle spec IDs (which
embed the node-scoped resource ID) as well as node-independent metric
spec IDs, and call it from the canonical lifecycle and stateful
evaluators, the powered-off resolver, and the disabled-threshold early
returns in both metric paths. Guest-wide sweep clears (metric clear on
stop, per-disk cleanup, tag suppression) now match the stable
instance+vmid identity across nodes too.
Reported by Johannes Strasser: a VM live-migrated between Proxmox
nodes stranded its pre-existing active alert with no way to clear it.
