0960e43a45 Optimisation mémoire api-anchorage avec base de données SQLite
**Motivations:**
- Réduction drastique de la consommation mémoire lors des ancrages
- Élimination du chargement de 173k+ UTXOs à chaque requête
- Stabilisation de la mémoire système sous charge élevée (50+ ancrages/minute)

**Root causes:**
- api-anchorage chargeait tous les UTXOs (173k+) via listunspent RPC à chaque ancrage
- Filtrage et tri de 173k+ objets en mémoire pour sélectionner un seul UTXO
- Croissance mémoire de ~16 MB toutes les 12 secondes avec 50 ancrages/minute
- Saturation mémoire système en quelques minutes

**Correctifs:**
- Création du module database.js pour gérer la base de données SQLite partagée
- Remplacement de listunspent RPC par requête SQL directe avec LIMIT 1
- Sélection directe d'un UTXO depuis la DB au lieu de charger/filtrer 173k+ objets
- Marquage des UTXOs comme dépensés dans la DB après utilisation
- Fermeture propre de la base de données lors de l'arrêt

**Evolutions:**
- Utilisation de la base de données SQLite partagée avec signet-dashboard
- Réduction mémoire de 99.999% (173k+ objets → 1 objet par requête)
- Amélioration des performances (requête SQL indexée vs filtrage en mémoire)
- Optimisation mémoire de signet-dashboard (chargement UTXOs seulement si nécessaire)
- Monitoring de lockedUtxos dans api-anchorage pour détecter les fuites
- Nettoyage des intervalles frontend pour éviter les fuites mémoire

078b36d404 Add pagination and search to hash list page
**Motivations:**
- La liste des hash est très longue (17k+ hash) et difficile à naviguer
- Besoin de rechercher un hash spécifique
- La colonne confirmations prend trop de place

**Root causes:**
- Pas de pagination, tous les hash sont affichés d'un coup
- Pas de fonctionnalité de recherche
- Colonne confirmations affiche un nombre alors qu'une coche suffit

**Correctifs:**
- Ajout de la pagination (50 hash par page)
- Ajout d'un champ de recherche pour filtrer par hash (recherche partielle)
- Remplacement de la colonne Confirmations par Confirmé avec coche ✓ (vert) ou ✗ (rouge)
- Navigation avec boutons Précédent/Suivant et affichage du nombre de pages

**Evolutions:**
- Meilleure navigation dans la liste des hash
- Recherche rapide d'un hash spécifique
- Interface plus compacte et lisible

970b06ee8f Fix: Automatic UTXO provisioning on each Bitcoin anchor transaction
**Motivations:**
- Fix insufficient UTXO amount error in anchor API
- Ensure continuous availability of usable UTXOs for anchor transactions
- Improve anchor transaction reliability and efficiency

**Root causes:**
- UTXO selection logic was too restrictive, rejecting UTXOs larger than needed
- No automatic provisioning of new usable UTXOs when existing ones were not suitable
- Algorithm prevented efficient use of available UTXOs

**Correctifs:**
- Refactored createAnchorTransaction() to provision 7 UTXOs of 2500 sats on each anchor
- Use single large UTXO to create 1 anchor output + 7 provisioning outputs + change
- Simplified UTXO selection: single large UTXO per transaction instead of multiple small ones
- Added UTXO provisioning logic in signet-dashboard
- Enhanced Bitcoin RPC methods in both api-anchorage and signet-dashboard
- Added documentation in fixKnowledge/api-anchorage-utxo-provisioning.md

**Evolutions:**
- Enhanced signet-dashboard with new pages (hash-list, utxo-list, join-signet, api-docs)
- Improved Bitcoin RPC client with better error handling and UTXO management
- Added cache files for hash and UTXO lists
- Updated api-faucet with improved server configuration
- Enhanced anchor count tracking
