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/
