feat(cmf): per-server O(1) attention override at serve time

Each managed local model row gains an O(1) selector (auto / off / all / deepN),
exported to the child `cortiq serve` as CMF_O1. "off" forces exact attention,
curing incoherent output from a too-aggressive `--o1` conversion hint without
re-converting the file; "all"/"deepN" force-enable it. Auto (default) follows
the hint recorded in the .cmf. Surfaced in /admin/api/cmf per-server status.
