fix(gateway): show other profiles in gateway status to prevent confusion

When multiple gateway profiles are running (e.g. default and wx1),
`hermes gateway status` can be misleading — stopping one profile's
gateway and checking status may still show the other profile's process
without indicating which profile it belongs to.

Add `_print_other_profiles_gateway_status()` which displays running
gateways from other profiles at the bottom of the status output:

    Other profiles:
      ✓ wx1              — PID 166893

This uses the existing `find_profile_gateway_processes()` and
`get_active_profile_name()` — no new dependencies.

Closes #19113
