refactor(routes): rename /agents and /agent-setup to /scouts and /scout-setup

Rename routes/agents.py → routes/scouts.py and routes/agent_setup.py →
routes/scout_setup.py. Update APIRouter prefix/tags in scouts.py to
/scouts and scouts. Update main.py router registration, device_ws.py
import, and test_journey_v2.py import/patch paths to use scout_setup.
