Add "maybe" status option and long-press functionality

This update introduces a new "maybe" status for entries, represented by a distinct UI button and background. Additionally, long-press functionality has been implemented, allowing users to toggle the "confirmed" status through prolonged interaction. UI components and styles have been updated to reflect these changes, improving usability.
