Drop dead route handlers that have an active replacement and zero callers
(frontend, backend, tests):
- create-lxc, create-lxc-smart -> superseded by POST /lxc/deploy
- clone-lxc -> superseded by container/{vmid}/clone
- {server_id}/lxc-templates -> duplicate of /lxc-templates/{server_id}
- dashboard/stats -> dashboard uses resources/all + alerts
- permissions (v1) -> superseded by permissions/v2
The identically-named ProxmoxClient/SecurityService methods are kept (they
back the surviving endpoints).
