branch1: root-path deployment variant with chat UI hidden

- BASE_PATH="" for deployment at www.ityb.me root (no /careerbot prefix)
- Root redirect route only registered when BASE is non-empty
- Add secondary /careerbot/uploads mount for backward compat with
  trunk-uploaded photo URLs (shared DB scenario)
- Hide chat FAB and chat panel on index.html (display:none)
