feat(sensor-proxy): improve turnkey setup experience with Pulse restart handling

- Update installer to use v4.32.0 Phase 2 binaries with file-based config
- Add automatic detection of Pulse service (systemd/hot-dev/docker)
- Add --restart-pulse flag for automatic Pulse restart in dev/test environments
- Default behavior shows clear instructions to restart Pulse manually (safe for production)
- Add prominent restart notice with command suggestions based on detected deployment
- Improve UX by making restart step impossible to miss
