Feature : Adding countdown for hike screen and exit pop up box upon ending

[ItsAdityaKSingh]

Is your feature request related to a problem? Please describe. There is no countdown on the hike screen for how long a hike is active.

Describe the solution you'd like Add a countdown timer instead of the time of expiry on the hike screen. Also, add a pop-up box asking the user to return home as the beacon has expired.

Additional context Any other suggestions or changes are open for discussion.
