As part of the UI Revamp work for summit, there will be a refactor of the frontend state management and this spike investigates and will break that into steps. 

The outcome of this spike will be clear steps towards achieving the overall goal that can be added to sprints. 

Spike Objectives
1. Assess current state - Document the structure and pain points of the existing store
2. Research patterns - Evaluate RTK's combineSlices and other modular patterns for breaking up large slices
3. Identify subdomains - Determine logical groupings for wizard state
4. Define file structure - Propose conventions for slices, selectors, and validators
5. Plan migration path - Break the refactor into incremental phases that minimize risk
6. Establish test strategy - Determine what coverage is needed before refactoring begins

Deliverable
A proposal document outlining the recommended approach, phased implementation plan, and any trade-offs considered.
