Subject: [PATCH] fix: use available instance types in allocation test to
 prevent flaky CI

The FilterUnavailableTypesAfterAllocation test picked a random 2-vCPU
type from the raw instance type map, which could include memory-hungry
types (e.g. r5a.large at 16 GB) that exceed host RAM on CI runners
(~15.6 GB). Now picks from the already-filtered available types list.
