chore(decommission): drop rustfs import shims — apply destroys LXC 800/801/802 (stage 2/2)

Stage 1 (#268) adopted the never-tofu-managed rustfs containers into
state (import run 1173: all three imported, plan 'No changes').
Removing the shims makes the next apply destroy the containers —
guest lifecycle fully through tofu, per owner rule.

-# TEMPORARY import shims — rustfs LXCs 800/801/802, decommission in progress.
-#
-# These containers were never tofu-managed, so the #259/#265 decommission
-# sweep could not destroy them (no state entry, nothing to plan). Owner rule:
-# ALL guest lifecycle goes through tofu — no manual pct/qm destroy, ever.
-# The tofu-clean path for unmanaged leftovers is import-then-destroy:
-#
-#   1. Merge this file, then adopt the containers into state via the
-#      pipeline's import hook:
-#        woodpecker pipeline create --branch master \
-#          --var PIPELINE=deploy-infrastructure \
-#          --var 'TOFU_IMPORT=proxmox_virtual_environment_container.rustfs_decommission["800"] saturn/800
-#        proxmox_virtual_environment_container.rustfs_decommission["801"] jupiter/801
-#        proxmox_virtual_environment_container.rustfs_decommission["802"] neptune/802'
-#   2. Follow-up PR deletes this file; the next apply (TOFU_APPLY=true)
-#      destroys the containers. Then this comment is history.
-#
-# Attributes are the bare minimum for a clean import + no-op plan: the
-# containers are stopped and stay stopped until destroyed.
