- Add /api/traffic/flow proxy route to hide TomTom API key from frontend
- Add tileset_hillshade and traffic config blocks to all three profiles
- Flip has_hillshade and has_traffic_overlay flags in home and regional profiles
- Minimal profile has config blocks but flags remain false (dormant)

Add profile-driven config infrastructure:
- config/profiles/{home,regional_pi,minimal_pi}.yaml templates
- lib/deployment_config.py loader (reads RECON_PROFILE env var)
- GET /api/config returns active profile as JSON (5min cache)
Frontend reads this on startup to determine tile source, defaults,
and feature flags. No existing behavior changed.
