Simplify CreateAppOptions and DefaultAppOptions into a single object

[isaacroldan]

WHY are these changes introduced?

We had two very similar objects: CreateAppOptions and AppCreationDefaultOptions

We are refactoring and unifying everything to just use CreateAppOptions.

WHAT is this pull request doing?

• Consolidates app creation options into a single CreateAppOptions interface
• Removes redundant name parameter from createApp method signatures
• Updates all callers to use the new unified options interface
• Ensures directory is consistently passed through creation options

How to test your changes?

1. Create a new app using shopify app init
2. Link an existing app using shopify app config link
3. Verify all app creation flows work as expected with proper options passed through

Measuring impact

• n/a - this doesn't need measurement, e.g. a linting rule or a bug-fix

Checklist

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