937646cc45 Daily backup to git cron, backup/restore scripts, docs 
**Motivations:**
- Export Signet and mining wallet backups to git with only 2 versions kept
- Document and add backup/restore scripts for signet and mining wallet

**Correctifs:**
- Backup-to-git uses SSH URL for passwordless cron; copy timestamped files only; prune to 2 versions; remove *-latest from backup repo

**Evolutions:**
- data/backup-to-git-cron.sh: daily export to git.4nkweb.com/4nk/backup
- save-signet-datadir-backup.sh, restore-signet-from-backup.sh, export-mining-wallet.sh, import-mining-wallet.sh
- features/backup-to-git-daily-cron.md, docs/MAINTENANCE.md backup section
- .gitignore: data/backup-to-git.log

**Pages affectées:**
- .gitignore, data/backup-to-git-cron.sh, docs/MAINTENANCE.md, features/backup-to-git-daily-cron.md
- save-signet-datadir-backup.sh, restore-signet-from-backup.sh, export-mining-wallet.sh, import-mining-wallet.sh

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/
