ncantu 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

- api-anchorage/src/bitcoin-rpc.js: Complete refactor of createAnchorTransaction()
- api-anchorage/src/routes/anchor.js: Enhanced anchor route
- api-anchorage/src/server.js: Server configuration updates
