Added `topic` tracking to posts and improved quoted post handling by linking quoted posts to their parent topic. Introduced error handling for decorators to prevent crashes and ensure smoother operation in case of unexpected issues. These changes enhance reliability and data consistency across related components.

Stop tracking `topic` from the post model to prevent error while updating a post from another.

 Refactor post-related page objects to simplify method usage and add new helper methods. Improve post stream specs with enhanced context handling and support for glimmer settings to ensure robust testing of post interactions.

Changed the assignment to use Ember's `set` method for properly updating the `topic` property on `quotedPost`. This ensures data bindings or observers are triggered correctly if applicable.

The `topic` property is now tracked to ensure proper reactivity and prevent issues when handling null values. Adjusted logic to avoid overwriting `topic` with null if already initialized, and updated code in quote-controls to use direct property assignment instead of `set`.
