Move a resource to another server

The Coolify API has no in-place server move, so destination.server and destination.network are not patchable fields. plan diffs them (projecting the server’s logical name, never its UUID) and marks any change as a recreate, distinct from an ordinary update — in JSON the item carries "requires_recreate": true:

-/+ Application.api must be recreated (destination changed: server "localhost" -> "hetzner-1")
    ~ Application.api.destination.server: "localhost" -> "hetzner-1"

apply refuses to update a resource whose destination changed — no partial PATCH is emitted, so the resource can never end up half-migrated with its old server silently kept:

cannot move application "api" to server "hetzner-1": destroy it first, then re-apply (Coolify has no in-place server move)

The supported choreography is destroy, then re-apply:

iac-coolify destroy infra/ --env staging --target api --auto-approve   # removes it from the old server
# edit destination.server in the manifest
iac-coolify apply infra/ --env staging --target api --auto-approve     # creates it on the new server

A destination.server that references a variable ("${env:STAGING_SERVER}") stays stable at plan time — references are resolved only at apply, so an unresolved reference never shows up as a phantom recreate, and destroy works without the variable set.
