Add Process UI Components to Core

Problem/Motivation

Add core UI components to the AI module for visualizing and managing AI processes, with real-time updates using Server-Sent Events (SSE).

Currently, there's no standardized way to:

• View process status and progress in real-time
• Stream updates without polling
• Manage running processes efficiently
• Display process history
• Provide continuous feedback for long-running operations
• Integrate process visualization with entities

Proposed resolution

1. Real-time Updates
   • SSE controller for process updates
   • Event stream handling
   • Real-time progress indicators
   • Stream reconnection handling
   • Fallback mechanisms
2. Views Integration
   • Process list view
   • Process status view
   • Custom views field handlers
   • Filterable/sortable process data
   • Bulk operations support
3. Process Display Components
   • Real-time status indicator
   • Streaming progress bar
   • Live token updates
   • Error display
   • Process control buttons
4. Entity Integration Framework
   • Local tasks (tabs) integration
   • Entity-specific process views
   • Contextual filters
   • Process history per entity
5. Stream Management
   • Connection handling
   • Error recovery
   • Bandwidth optimization
   • Multiple stream coordination
   • Client state management

API changes

• New SSE endpoints
• New local tasks
• Stream handling services
