cleanup: remove /api/config handler (extraction #2 shadow) (#10)

* cleanup: remove /api/config handler (extraction #2 shadow)

recon's /api/config Flask handler (lib/api.py) is edge-shadowed since
extraction #2 — navi-config (:8422) serves the route via nginx on
navi.echo6.co. The recon-side handler is dead at the edge; remove it.

lib/deployment_config.py is KEPT: get_deployment_config() still has many
in-process consumers (lib/api.py:1237 /api/landclass has_landclass gate,
google_places.py, place_detail.py x4, offroute/router.py). Only the
/api/config HTTP handler is removed; the import at api.py:27 stays.

* cleanup: refresh deployment_config docstring (drop /api/config reference)

The module docstring still said get_deployment_config() was "for use by the
/api/config endpoint" — that handler was removed in the parent commit. Rewrite
to reflect the actual 5 in-process consumers (landclass gate, google_places,
place_detail ×4, offroute/router.py profile.offroute.*).
