  1. [CLI] Exclude unset service groups from requests (#4256) 

    `ServiceConfigurationParams.groups` was added in 0.21.3 (#4177) along
with a model serializer that popped `groups` from every dump and
re-emitted it as the legacy `replicas: [{count: ...}]` shape. Living on
the model, it applied in both directions, so a 0.21.3 client never put
`groups` on the wire.

PR #4248 removed that serializer in favor of a server-side patch gated
on `client_version < 0.21.3`. That covers server -> old client, but
nothing replaced client -> old server, so 0.21.4 clients always send
`configuration.groups` and servers before 0.21.3 reject it as an extra
field.

Exclude service `groups` when unset, as already done for
`TaskConfiguration.groups`. This covers all three client paths that send
a `run_spec`: `get_plan`, `apply`, and `gpus/list`.

Fixes: #4255
