fix: fixed page popped out of context during tutorial and details page bug

[Mastermind-sap]

Description

• I have fixed the bug where the page or widget is popped out of context while the tour or tutorial is still going on. Have used PopScope to handle it.
• Fixed the details page update bug where it forces user to push Yes in save changes dialog box to go back to home page.
• Also removed third party dependency double_back_to_close_app and simulated the double back to exit in home page using PopScope
