feat: team-specific subdomains + portal tim

- create_team now takes label -> slug -> <slug>.gemastik.imrnes.team
- ensure_team_domains() writes Traefik dynamic config (gemastik-teams.yaml)
- team portal at /team/<idx> (public, shows chall ports, SSH, submit form)
- /api/team/<idx>/info + /api/team/<idx>/status (server-side receiver auth)
- UI: name inputs per team (set count -> labels), domain link in card
- delete team endpoint drops its domain
