Admin UI Extensions - Examples 2024-10

Summary

This PR adds comprehensive code examples for all Admin UI Extension Target APIs in the 2025-10 version. All examples follow the modern Preact pattern established in POS UI Extensions, using .jsx files with the global shopify object.

We detected some changes in packages/*/package.json or packages/*/src, and there are no updates in the .changeset directory. If the changes are user-facing and should cause a version bump, run yarn changeset to track your changes and include them in the next release CHANGELOG. If you are making simple updates to repo configuration, examples, or documentation, you do not need to add a changeset.

There are a handful of example files that we can actually clean up from this PR, given that some of the APIs don't exist in this version. I've added some comments about that below.

🚀 🚀 Also, approving, pending these suggestions are considered for this version as well: #3823 (review)

[mcvinci]

I don't think we need all these examples in this version, given the Picker API isn't available?

[mcvinci]

Same here. I don't think we need these examples in this version, given the Discount Function Settings API isn't available in this version.

[mcvinci]

Same here. This API isn't available in this version, so we can remove the examples.

[mcvinci]

Should Render API isn't available in this version, so we should remove the example files.
