refactor: rename GPU service to cleaner naming convention

GPU Service Renaming - Complete:
✅ GPU SERVICE RENAMED: Simplified GPU service naming for consistency
- systemd/aitbc-multimodal-gpu.service: Renamed to aitbc-gpu.service
- setup.sh: Updated all references to use aitbc-gpu.service
- Documentation: Updated all references to use new service name
- Reason: Cleaner, more intuitive service naming

✅ RENAMING RATIONALE:
🎯 Simplification: Cleaner, more intuitive service name
📝 Clarity: Removed 'multimodal-' prefix for simpler naming
🔧 Consistency: Matches standard service naming patterns
🎨 Standardization: All services follow aitbc-{name}.service pattern

✅ SERVICE MAPPING:
🚀 aitbc-multimodal-gpu.service → aitbc-gpu.service
📁 Configuration: No service.d directory to rename
⚙️ Functionality: Preserved all GPU service capabilities

✅ SETUP SCRIPT UPDATES:
📦 install_services(): Updated services array with new name
🚀 start_services(): Updated systemctl start command
🔄 setup_autostart(): Updated systemctl enable command
📋 Status Check: Updated systemctl is-active check

✅ DOCUMENTATION UPDATES:
📚 documented_AITBC_Enhanced_Services__8010-8016__Implementation.md: Updated service path
📚 ENHANCED_SERVICES_IMPLEMENTATION_GUIDE.md: Updated all systemctl commands
📋 Service management: Updated manage_services.sh commands
🎯 Monitoring: Updated journalctl and status commands

✅ COMPLETE SERVICE LIST (FINAL):
🔧 aitbc-wallet.service: Wallet management
🔧 aitbc-coordinator-api.service: Coordinator API
🔧 aitbc-exchange-api.service: Exchange API
🔧 aitbc-blockchain-node.service: Blockchain node
🔧 aitbc-blockchain-rpc.service: Blockchain RPC
🔧 aitbc-gpu.service: GPU multimodal processing (RENAMED)
🔧 aitbc-marketplace.service: Marketplace
🔧 aitbc-openclaw.service: OpenClaw orchestration
🔧 aitbc-ai.service: AI capabilities
🔧 aitbc-learning.service: Learning capabilities

✅ BENEFITS:
✅ Cleaner Naming: More intuitive and shorter service name
✅ Consistent Pattern: All services follow same naming convention
✅ Easier Management: Simpler systemctl commands
✅ Better UX: Easier to remember and type service name
✅ Maintainability: Clearer service identification

✅ CODEBASE CONSISTENCY:
🔧 All systemctl commands: Updated to use new service name
📋 All service arrays: Updated in setup script
📚 All documentation: Updated to reference new name
🎯 All references: Consistent naming throughout codebase

RESULT: Successfully renamed GPU service to cleaner naming convention, providing more intuitive and consistent service management across the entire AITBC ecosystem with standardized naming patterns.
