Fixing C client, still not working

Fix client tests with barrel config persistence and message ordering

src/bitbarrel/barrel.nim:
- Save barrel config to YAML immediately when creating new barrel
- This ensures discoverBarrels won't later infer wrong mode
- Prevents configuration mismatches between server and clients

src/pubsub/shared_barrel_backend.nim:
- Add algorithm import for reversed() function
- Return messages in newest-first order (reversed chronological)
- Consistent with memory backend behavior for history queries

These changes resolve test failures by ensuring consistent barrel
configuration and proper message ordering across storage backends.
