DO NOT MERGE: Remove all conditional logic around App Management being disabled

[amcaplan]

WHY are these changes introduced?

Completes https://github.com/Shopify/develop-app-inner-loop/issues/2343

Removes the App Management feature flag and makes it a default part of the CLI's functionality. This should be merged when App Management is ready to be rolled out to all eligible organizations.

WHAT is this pull request doing?

• Removes the USE_APP_MANAGEMENT_API environment variable and related checks
• Removes any behavior implementing a special case where App Management is disabled

How to test your changes?

1. Deploy an app using shopify app deploy
2. Verify organizations are fetched from both Partners and App Management APIs
3. Test app creation and management workflows to ensure they work without the feature flag

Checklist

• I've considered possible cross-platform impacts (Mac, Linux, Windows)
• I've considered possible documentation changes

Differences in type declarations

We detected differences in the type declarations generated by Typescript for this branch compared to the baseline ('main' branch). Please, review them to ensure they are backward-compatible. Here are some important things to keep in mind:

• Some seemingly private modules might be re-exported through public modules.
• If the branch is behind main you might see odd diffs, rebase main into this branch.
