Which issue(s) this PR fixes:

What this PR does / why we need it:

Adds longhornctl check upgrade, a pre-check for V2 instance-manager rolling live upgrades.

The command validates V2 feature availability, upgrade compatibility, attached-volume constraints, volume health, replica topology, and required instance-manager/node/block-disk readiness. It reports unsupported and temporarily not-ready conditions before an upgrade starts.

Special notes for your reviewer:

This command is intentionally V2-only. V1 engine-image upgrades are volume-by-volume and are not covered by this check.

Additional documentation or context

Usage:

longhornctl check upgrade
