[Task](compute): rework the Instance Create Dialog

[andypf]

Rework the Instance Create Dialog

The current Instance Create Dialog uses a very large image select grouped by provider (KVM, VMware, bare metal) which makes it hard to use and scale. This task covers the research, planning, and implementation phases to improve the dialog UX and modernize the implementation.

🎯 Problem Statement

• jQuery-based implementation (legacy)
• Massive image selector → difficult to navigate
• No filters or search capability
• Scalability issue as image catalog grows

📋 Scope

1. ✅ Migrate to React (remove jQuery)
2. 🔍 Research UX options (steps, filters, search)
3. 👥 Collect user feedback
4. 📈 Define phased implementation plan
5. 🚀 Implement chosen solution

🎨 Possible Approaches

Option	Pros	Cons
Multi-step wizard	Guided flow	More clicks
Filter checkboxes	Fast filtering	Screen space
Search + grouping	Scalable	Complex impl.
Tabbed providers	Clean UI	Provider switch

✅ Expected Outcome

• Modern React dialog
• Scalable image selection (filters/search/steps)
• Phased implementation plan
• Improved UX validated with users

📏 Success Criteria

• React migration complete
• User testing confirms improved UX
• Implementation plan approved
• Dialog handles 1000+ images smoothly
