On 409 (team already exists), list the org teams to find the operators
team id, then unconditionally PATCH to the desired settings via
org_edit_team. This self-heals a team that was created with the wrong
shape by an older code path (missing units, wrong permission) without
touching membership (separate endpoint, operator-managed).
Addresses mara's review: 'shouldnt we get, then change, then update'.
Unconditional PATCH is simpler than GET→diff→conditional PATCH and safe
here since we own units/permission/description fully.
