Enhance distributed agent architecture with full mode support and reliability

Agent improvements:
- Add process verification (0.5s delay + poll check) for sensor, pager, APRS, DSC modes
- Prevents silent failures when SDR is busy or tools fail to start
- Returns clear error messages when subprocess exits immediately

Frontend agent integration:
- Add agent routing to all SDR modes (pager, sensor, RTLAMR, APRS, listening post, TSCM)
- Add agent routing to WiFi and Bluetooth modes with polling fallback
- Add agent routing to AIS and DSC dashboards
- Implement "Show All Agents" toggle for Bluetooth mode
- Add agent badges to device/network lists
- Handle controller proxy response format (nested 'result' field)

Controller enhancements:
- Add running_modes_detail endpoint showing device info per mode
- Support SDR conflict detection across modes

Documentation:
- Expand DISTRIBUTED_AGENTS.md with complete API reference
- Add troubleshooting guide and security considerations
- Document all supported modes with tools and data formats

UI/CSS:
- Add agent badge styling for remote vs local sources
- Add WiFi and Bluetooth table agent columns
