feat: add provisioning lifecycle actions

Rename Deployments to Provisioning with compatible redirects and APIs. Add durable Start, Restart, Stop, and Rebuild operations alongside Create and Destroy; rebuild wipes the instance and recreates it in the same slot and port.

Add lifecycle, migration, recovery, and Komodo command tests. Type checks and production build pass; the full suite retains a telemetry assertion failure reproduced on the unchanged branch.
