fix: center login form, simplify startup logs

login.html:
- Fix token input/button centering (remove Bootstrap navbar pull-left)
- Update token hint: GATEWAY_TOKEN is default, JUPYTER_TOKEN overrides
- Remove stale "default token is huggingface" text

start.sh:
- Silence GATEWAY_TOKEN auto-enable message (was noisy debug output)
- Redirect pip install output to /dev/null, show one-liner status
- Remove "JUPYTER_TOKEN not set — using GATEWAY_TOKEN" noise
- Replace "DEV_MODE enabled (false) — starting JupyterLab..." with clean
"Terminal : starting / started / installed" format
- Remove "Jupyter terminal disabled for this boot" noise
- Remove "Private :" line from startup summary
- Clean DevData restore messages to match consistent format
