fix: prefer reserved capacity during consolidation

[capy-ai]

Summary

• prefer reserved offerings when consolidating mixed reserved/on-demand node pools
• allow reserved consolidation to split existing on-demand nodes into multiple reserved replacement NodeClaims when that lowers effective cost
• keep reserved nodes from being deleted into on-demand capacity while paid ODCR inventory is available
• update Go/x dependencies so make vulncheck passes on current advisories

Tests

• go test ./pkg/controllers/disruption -run '^$'
• go test ./pkg/controllers/disruption -run TestAPIs -ginkgo.focus='Reserved Capacity' -count=1
• make vulncheck

Full disruption suite was attempted after installing envtest binaries, but fake-clock TTL specs hung until the Go test timeout; the reserved-capacity-focused specs above pass.
