Prevent non-logged in users from accessing the matching chat & profile pages

[HirdayGupta]

Instructions:

• Do this work on a new Branch from development
• If users aren't logged in, for now just show a popup on these pages, prompting the users to login and redirecting them to the log in screen
• investigate potential issues with this approach related to navigation and see what you can do about them
  • e.g. on redirecting to log in screen, what happens when user clicks check menus again? things like that...
