fix: expose remaining settable properties via :report

Adds the missing raw/global/computed report keys for ten settable properties across the ps, builder, scheduler, proxy, openresty, nginx, and scheduler-k3s plugins so external tooling can verify drift through `:report --format json`. The scheduler-k3s `token` is masked as `*******` in default stdout output and only unmasked when the report is requested via `--format json` or when the flag is queried explicitly by name; the same explicit-query unmasking rule is extended to the existing traefik `dns-provider-<env_var>` keys.
