feat: complete Phase 1 MVP - add agent executor and WebSocket real-time updates

Agent Executor Service:
- BaseAgent class with LLM integration via LiteLLM proxy
- AgentExecutor service that processes pending executions every 5 seconds
- Action execution: create_subtask, update_status, send_notification, add_comment
- Approval workflow: CxO level agents require user approval before execution
- Telegram notifications for approvals and completions
- Error handling and execution status tracking

WebSocket Real-Time Updates:
- WebSocket endpoint at /ws/opc for real-time task updates
- ConnectionManager for broadcasting to all connected clients
- Frontend WebSocket client with auto-reconnect
- Live updates for task create/update/move/delete actions
- Agent execution status broadcasts

Integration:
- Agent executor starts on dashboard startup
- Task router broadcasts WebSocket updates on all mutations
- Frontend OPC page subscribes to WebSocket and updates UI in real-time
- Agents (PM, CTO, COO) can now execute tasks autonomously

Phase 1 MVP Complete:
✅ PostgreSQL database with full schema
✅ Task CRUD API with automatic time tracking
✅ Kanban board with drag-and-drop
✅ Agent executor service with LLM integration
✅ WebSocket real-time updates
✅ 3 core agents ready to execute

Next: Agent panel UI, email notifications, PDF invoicing
