Matt Johnson 565e774864 Add navi-config service (extraction #2 PR-B)
New services/navi_config/ on :8422, mirroring recon's /api/config contract:

  - config_route.py: GET /api/config -> jsonify(get_deployment_config())
    with Cache-Control: public, max-age=300 (byte-for-byte recon's response).
  - config_loader.py: faithful port of recon lib/deployment_config.py. Reads
    RECON_PROFILE (default "home") and NAVI_CONFIG_PROFILES_DIR (default
    /opt/recon/config/profiles, so it serves the SAME files recon does during
    cutover). yaml.safe_load, module-level cache. Lazy load (vs recon's eager
    import-time load) so the module imports cleanly off-VM and a missing
    profile surfaces as HTTP 500 at request time rather than a failed import.
  - admin.py: /api/admin/navi-config/info per handoff §4.5, require_auth gated.
    env values (NAVI_CONFIG_PROFILES_DIR, RECON_PROFILE) are non-secret paths/
    names, shown as-is (no mask_key); dependencies=[]; filesystem reports the
    active profile path + exists/readable.
  - app.py: create_app() factory mirroring navi_traffic, same metrics wiring;
    resets the loader cache per instance so each worker/test reloads fresh.

Deploy artifacts: systemd unit (:8422) and an nginx snippet using
`location ^~ /api/config` (the ^~ convention from extraction #1 so the asset
.png/.css regex can't shadow it). No proxy_cache zone — the response is
already cached in-process and via Cache-Control: max-age=300; emits a literal
X-Cache-Status: BYPASS for parity with navi-traffic.

Adds PyYAML>=6 to deps. Tests (services/navi_config/tests): 200 + parsed dict,
Cache-Control header, RECON_PROFILE override, default=home, missing profile=500.
