feat: full node isolation - use node-specific swapper_url and router_url from DB

- Add migration 041_node_local_endpoints.sql
- Add get_node_endpoints() to repo_city.py
- Update routes_city.py to use DB endpoints instead of hardcoded URLs
- Update node-guardian-loop.py to use NODE_SWAPPER_URL/NODE_ROUTER_URL env vars
- Update launchd plist for NODE2 with router URL
