fix: default JUPYTER_ENABLED to true, remove baked DEV_MODE from image

Dockerfile: remove ENV DEV_MODE=false baked at build time — was causing
start.sh auto-enable check to fail (DEV_MODE non-empty → condition skipped).
DEV_MODE is now unset at runtime by default; HF Space Variable overrides
still work normally.

health-server.js: simplify JUPYTER_ENABLED logic — true by default, only
false when DEV_MODE=false or HUGGINGCLAW_JUPYTER_ENABLED=false is explicitly
set by the user.
