Fix Grafana dashboard datasource, add Grid Singularity skill

- Fix PostgreSQL datasource uid in Grafana dashboard
- Update datasource to point to FlexMeasures DB (flexmeasures-db:5432)
- Dashboard now shows real data from Cariflex simulator
- Add Grid Singularity skill (gsy-e, gsy-framework, gsy-e-sdk)

+# Skill Grid Singularity - Cariflex Energy
+
+## Description
+Intégration des outils Grid Singularity (GSy) pour le projet Carifflex.
+Grid Singularity est une plateforme open source pour les marchés décentralisés d'énergie.
+
+## Source
+https://github.com/gridsingularity
+
+## Repos principaux
+
+| Repo | Description | Stars | Langage |
+|------|-------------|-------|---------|
+| `gsy-e` | Grid Singularity Energy Exchange | 88 | Python |
+| `gsy-framework` | GSy services framework | 8 | Python |
+| `gsy-e-sdk` | Client SDK for Grid Singularity Exchange | 3 | Python |
+| `gsy-matching-engine-sdk` | SDK for Myco matching agents | 0 | Python |

+
+## Installation
+
+### 1. Cloner les repos
+```bash
+cd /home/eric/cariflex/tools
+
+# Energy Exchange (principal)
+git clone --depth 1 https://github.com/gridsingularity/gsy-e.git
+
+# Framework
+git clone --depth 1 https://github.com/gridsingularity/gsy-framework.git
+
+# SDK
+git clone --depth 1 https://github.com/gridsingularity/gsy-e-sdk.git
+```
+
+### 2. Installation gsy-e
+```bash
+cd gsy-e
+pip install -e .
+```
+
+### 3. Installation SDK
+```bash
+cd gsy-e-sdk
+pip install -e .
+```
+
+## Architecture Grid Singularity
+
+### Composants
+| Composant | Rôle |
+|-----------|------|
+| **Energy Exchange** | Marché décentralisé d'énergie |
+| **Matching Engine** | Appariement offres/demands |
+| **SDK Client** | Interface pour participants |
+| **Blockchain DEX** | Transactions décentralisées |
+
+### Intégration Cariflex
+```
+Cariflex CEM → gsy-e-sdk → Grid Singularity Exchange
+                                    ↓
+                              Matching Engine
+                                    ↓

+```
+
+## Utilisation SDK
+
+### Connexion au Exchange
+```python
+from gsy_e_sdk import GSyEClient
+
+client = GSyEClient(
+    gsy_e_api_url="https://api.gsy-e.io",
+    username="cariflex",
+    password="***"
+)
+
+# Submit buy/sell offers
+client.submit_buy_offer(
+    energy_kwh=100,
+    price_eur_mwh=50,
+    time_slot="2026-06-09T12:00:00Z"
+)
+```
+
+### Récupérer les prix du marché
+```python
+market_prices = client.get_market_prices()
+for slot in market_prices:
+    print(f"{slot.time}: {slot.price} €/MWh")
+```
