Refactored `solved_spec.rb` to make `accepted answer` assertions more explicit and structured. Consolidated selector handling and clarified expectation of the expanded quote behavior.
Refactored the `solved-accepted-answer` component to utilize the `PostQuotedContent` component, simplifying the structure and removing redundant code. Updated system tests to verify behavior of expandable accepted answer quotes. Added new compatibility entry for version `< 3.5.0.beta7-dev` and included TODO comments regarding event handling for Glimmer Post Stream.
