Store platform in Activity

[lambdan]

• Added a platform CharField for Activity. Defaults to pc (existing activity will get that value)
  • There's probably a prettier way to add the column to existing databases. I tried using Playhouse Migrations, which worked, once. If you restarted the app, it would complain about the column already existing, so just using a raw SQL statement like this was much simpler, albeit ugly.
• If activity.platform is present in the Discord activity that is used (eg ps5)
  • If not available, pc will be used
  • Steam Deck (Decky Discord Activity) has a special case
• Added a application_id_from_activity() function, because PS5 activity seems to be missing application_id. Not sure if using activity.name is a good call.
