recon: remove /api/traffic/flow handler (now served by navi-traffic, extraction #1)

Browse source 
The /api/traffic/flow/<z>/<x>/<y>.png handler is dead code in recon. As of
extraction #1 of the recon<->Navi decoupling, this path is served by the
standalone navi-traffic service. Live request flow is now:

    Caddy (CT 101, navi.echo6.co @authed_api, forward_auth)
      -> nginx :8440 (location ^~ /api/traffic/ -> proxy_cache traffic_cache)
        -> navi-traffic gunicorn :8421 (services/navi_traffic)

Cutover verified live: authenticated browser fetch to
https://navi.echo6.co/api/traffic/flow/... returns 200 image/png with
X-Cache-Status MISS then HIT (120s cache), Server: gunicorn.

navi-backend (github.com/zvx-echo6/navi-backend):
  - dae54f3  Initial scaffold: navi-backend + navi-traffic
  - 311cb8f  nginx: use ^~ prefix on /api/traffic/ to beat .png regex catch-all

Caddy cutover (@authed_api upstream 8420 -> nginx 8440) applied on Utility
CT 101. Also drops the now-unused make_response flask import (no other uses
in lib/api.py). os and http_requests remain (used elsewhere).
