fix: JupyterHub DB path + user eric + OR mbtiles bounds + Hermes Dashboard

- Fix JupyterHub: sqlite db_url absolute path (was double-nested /srv/jupyterhub/srv/jupyterhub)
- Create user eric as admin in JupyterHub (id=2, authorized)
- Fix OpenRemote mbtiles: bounds metadata = world (-180,-85,180,85) for free zoom
- OR map API confirmed working: center=[-61,14.5], minZoom=0, bounds=Martinique
- Add Hermes Dashboard WebUI + TUI chat service (localhost:9119, auto-start at boot)
- Add generate_martinique_mbtiles.py script (future tile generation)

Known issues:
- JupyterHub spawn timeout (singleuser server slow to start, increased to 120s)
- OR mbtiles still contains Netherlands vector tiles (need Martinique tiles)
- Kafka, Trino still in restart loop (separate fix needed)

+|-----------|--------|----------|----------|
+| kafka-1, kafka-2 | Restarting | `zookeeper.connect` manquant | Ajouter ZK conn string |
+| trino | Restarting (100) | `node.environment` null | Ajouter `node.environment=production` au config |
+| jupyterhub | Restarting (1) | DB path `/srv/jupyterhub/srv/jupyterhub` n'existe pas | Corriger `JUPYTERHUB_CRYPT_KEY` ou créer le directory |
+| honcho-api-1 | Exited (1) | Host `database` non résolu | Vérifier réseau/connectivité PostgreSQL |
+| frost_allinone-web-1 | Exited (137) | OOM killed | Augmenter memory limit ou réduire services |
