ENG-3014 Fix setting role when changing team

[burnpiro]

Note

Low Risk
Small CLI config change that only affects local config state; low risk aside from potentially storing an incorrect role if the team lookup fails or returns unexpected data.

Overview
Fixes missing role persistence when switching teams via config. prime config set-team-id now looks up the team’s role from the teams list and passes it into Config.set_team(...), so team_role is updated/cleared consistently with team_id (matching the login flow behavior).
