fix(admin): show non-Docker update steps when not running in Docker (#1269)

The "How to Update" modal always rendered Docker commands and claimed the instance runs in Docker, even on bare-metal / LXC installs like Proxmox Community Scripts. It now branches on the is_docker flag the backend already returns: non-Docker installs get a generic "re-run your install method" note plus a link to the update guide. Docker stays the default when the flag is absent, so existing installs are unaffected.
