Add push notifications for bet requests and bet status changes

[c-o-l-i-n]

This would require a Supabase Edge Function.

1. Bet request

   • There is a database trigger for when a bet is created
   • On creation, a push notification is sent to the opponent
   • If possible, tapping on the notification routes to the betting dashboard
   • If possible, there are options to accept or reject the bet after "long pressing" the notification
   • The notification looks like this:
   • 👀 [Requester] bets you [X] points that [description].
   • 👀 [Requester] bets you [description]. [Requester] wagers [X] points, you wager [Y] points.

2. Bet canceled by GM

   • There is a database trigger for when a bet changes
   • If the status changes, and the new status is canceled_by_gm, then the requester AND opponent receive a notification
   • The notification looks like this:
   • 😵 The GM canceled your bet against [other player]

3. Bet rejected

   • Using the same database trigger for when a bet changes
   • If the status changed, and the new status is rejected, then the requester receives a notification
   • The notification looks like this:
   • 😔 [Opponent] rejected your bet

4. Bet accepted

   • Using the same database trigger for when a bet changes
   • If the status changed, and the new status is active, then the requester receives a notification
   • The notification looks like this:
   • 😎 [Opponent] accepted your bet

5. Bet settled

   • Using the same database trigger for when a bet changes
   • If the status changed, and the new status is requester_won, opponent_won, or push, then requester AND the opponent receive a notification
   • The notification looks like this:
   • 🥳✅ You won [X] points from your bet against [other player]
   • 🥲❌ You lost [X] points from your bet against [other player]
