kaffa 4e7d0a8969 fix: Improve error handling and reliability ...

4. Pool exhaustion - explicit error
   - Add NoAvailablePoolError exception class
   - find_available_pool() now raises instead of returning None
   - haproxy_add_domain() catches and returns user-friendly error

5. haproxy_add_server - disk-first pattern
   - Save to config FIRST, then update HAProxy
   - If HAProxy update fails, rollback config automatically
   - Prevents inconsistency between disk and runtime

6. Wildcard removal - log failures
   - Changed silent pass to logger.warning()
   - Failures now visible in logs for debugging
   - Does not block domain removal operation
