Center Meditation Timer

This update brings more reliable meditation sessions and many improvements to everyday use: - Open session duration directly from the timer screen, while the left button still opens your overview. - Fixed completion alerts using the wrong sound when the screen is off. - Added clearer guidance for enabling screen-off sounds when alarm permission is disabled. - Fixed an issue that could interrupt an active session when returning to the timer view. - Improved reminder scheduling and cancellation to prevent outdated or unwanted alerts. - Improved Apple Watch session syncing to address missing and duplicate history entries. - Fixed saving an existing custom duration without first changing the picker. - Improved session history: add a session even when your history is empty, with better handling of save and deletion errors. - Protected unsaved session entries from accidental swipe dismissal. - Added a retry option when session history cannot load at startup. - Refined settings search with a theme-colored highlight and improved focus behavior on Mac. - Added donation history so you can review your past support. - Added a convenient way to share Center with someone who could use a quiet moment. Thank you for making Center part of your practice.
