💡 Description

• Moved default browser user default to DefaultBrowserUtil, much cleaner than having this under the RatingPromptManager
• Change logic of rating prompt to latest requirements discussed in Document and the task description. This implies we remove the CumulativeDaysOfUseCounter code.
• Call the rating prompt on init of BVC so we show it on the start of the application
• Remove rating prompt from dependency container as its not needed there anymore
