feat: notify user to tap card to update balance

[aniruddha-adhikary]

Premise

Users may often forget to tap their own card to sync with the app. We should have an opt-in able feature to remind them.

Implementation

• WorkManager on Android and UNTimeIntervalNotificationTrigger on iOS.
• There should be a setting to enable this notification. By default can be off.
  • We can show an Alert to a user when they are "too late to scan" risking lost history. (Definition To be discussed)
• The notification frequency cannot the bother the user.
  • We can analyze the frequency of MRT pass usage to figure out how frequently the user should tap. Set the notification interval accordingly.
  • We should have a cutoff point where MRT use is so low the person doesn't need a reminder at all.
  • Initially, the default can be every 3 days
