Add docs for how to handle loading and error states in new page components

[Chucks1093]

Summary

New page components added by contributors handle loading and error states inconsistently — some show nothing while loading, others crash on error. A documented pattern for how every page component should handle these three states (loading, error, data) removes ambiguity.

Scope

• Document the three-state pattern: loading → show skeleton, error → show error UI with retry, data → render content
• Specify which skeleton component to use for each content type
• Explain when to use the error boundary vs an inline error state
• Include a minimal worked example showing all three states in one page component

Acceptance Criteria

• Three-state pattern is documented
• Skeleton component guidance is included
• Error boundary vs inline error decision is explained
• Worked example covers all three states

ETA: 12 hours

Hi team, I’d love to take this on!

I am a software engineer focused on building predictable systems, writing clean code, and uncovering subtle edge cases. I'm ready to dive into these requirements and deliver a highly secure, reliable solution.

I will deliver:

Defensive Implementation: Build out the core logic using explicit type safety and strict validation boundaries to neutralize potential runtime errors or logical oversights.

State & Schema Alignment: Update the underlying data schemas, backend logic, and API contracts symmetrically to prevent data fragmentation or desynchronization across layers.

Component Optimization: Refactor or introduce relevant interface blocks to handle loading states, success frames, and recovery triggers gracefully.

Bulletproof Test Coverage: Author comprehensive regression and property-based tests within our existing framework to guarantee long-term maintenance safety in CI.

Ready for assignment to drop a complete, robust PR immediately!
