feat: 🎸 Update how we store tokens in indexed-db (#2223)

Added logic to make the list tokens stored in indexed DB more granular.
I get a hash of the query parameters that will get sent to the controller
and use that as the id for the token. This also means extra logic for when
a token is invalid as we will need to delete all tokens of the same
resource type.
