fix(notification): word --all confirmations and flag values clearly

notification mark-read --all asked "Marked as read all … ?"; each command now asks in its own words, such as "Pin all unread notifications in your inbox?". The status and type filters list their values in help, the api parameter flags read like gh's, and tea auth login --help aligns its method list.
