refactor(web): replace all hardcoded SVG icons with lucide-react

Unify icon usage across the entire frontend by replacing 67 hardcoded
SVG icons with lucide-react components across ~25 files. This improves
consistency, maintainability, and reduces bundle duplication.

Key replacements:
- Sidebar nav: Zap, LayoutDashboard, Bot, Workflow, BookMarked, etc.
- MCP forms: Loader2, XCircle, Trash2
- Monitoring: Sparkles, MessageSquare, CheckCircle2, RefreshCw, etc.
- Cards: Clock, Star, Workflow, Hexagon, Puzzle, Github, etc.
- Misc: Paperclip, AudioLines, CloudUpload, Layers, Heart, Smile

Zero hardcoded <svg> tags remain in .tsx files.
