b3973ddc41 Add transaction statistics endpoints and systemd services 
**Motivations:**
- Add transaction statistics endpoints (avg-fee, avg-amount) for dashboard display
- Fix difficulty parsing issue when Bitcoin RPC returns string instead of number
- Add systemd service files for proper service management
- Update dashboard UI to display transaction statistics

**Root causes:**
- Bitcoin RPC can return difficulty as string, causing type issues
- Missing API endpoints for transaction statistics in dashboard

**Correctifs:**
- Fix difficulty parsing to handle both string and number types
- Add proper type conversion for blockchainInfo.difficulty

**Evolutions:**
- Add /api/transactions/avg-fee endpoint returning fixed 1200 sats fee
- Add /api/transactions/avg-amount endpoint returning fixed 1000 sats amount
- Add systemd service files for api-faucet and signet-dashboard
- Enhance dashboard UI with transaction statistics display
- Update anchor_count.txt

**Pages affectées:**
- signet-dashboard/src/server.js
- signet-dashboard/public/app.js
- signet-dashboard/public/index.html
- signet-dashboard/signet-dashboard.service

e34b6ee43a Fix UTXO selection and race condition in anchorage API 
**Motivations:**
- Resolve insufficient UTXO amount errors when wallet has many small UTXOs
- Prevent race conditions when multiple anchor requests arrive simultaneously
- Improve signet dashboard functionality and documentation

**Root causes:**
- API tried to find a single UTXO large enough instead of combining multiple UTXOs
- No mutex mechanism to prevent concurrent transactions from using the same UTXOs
- UTXOs in mempool still appear as available in listunspent before block confirmation

**Correctifs:**
- Implement coin selection algorithm to combine multiple UTXOs when needed
- Add mutex-based locking mechanism to serialize UTXO access
- Filter locked UTXOs during selection to prevent double spending
- Properly handle change output when combining multiple UTXOs
- Lock UTXOs during transaction creation and unlock after mempool broadcast

**Evolutions:**
- Enhance signet dashboard with improved Bitcoin RPC integration
- Update mempool documentation
- Add comprehensive fix documentation in fixKnowledge/
