[Components content]: Examples for 2025-07

[SteveSill]

Summary

Rewrites all code examples and descriptions for the 36 admin UI extension components in the 2025-07 API version. The existing examples were minimal placeholders (single-prop demos, missing descriptions, no real use cases). This PR replaces them with examples that show devs how to use each component in realistic extension scearios.

What changed

Example code (216 files): Each component now has 3 examples, each with a .ts (imperative) and .tsx (React) version. Examples use real extension targets like admin.product-details.action.render and block.render, and demonstrate actual patterns developers need — querying the GraphQL Admin API, posting to backend endpoints, handling form submission, validating input, and working with data.selected, close(), and navigation.

Documentation (36 .doc.ts files + 65 React .doc.ts files): Every defaultExample and examples section has been updated with:

• Action-oriented titles (5 words or fewer)
• Two-sentence descriptions following the Shopify dev docs style guide: first sentence explains the business use case, second sentence covers the technical implementation
• Links to related components and APIs where they help the reader (1-2 per description)

Prop validation: All props used in examples have been validated against the actual 2025-07 TypeScript type definitions to ensure no example references a prop, value, or component that doesn't exist in this version.
