Add buying subscription using in-app points

[ArtemLymarenko]

Let's make it more readable:

We need to enable users to purchase a subscription using in-app points, (price basic - 500 points, pro - 1000points).

1. Expand the subscription service to include the option to purchase using points.
   - Utilize trial periods on Stripe (refer to Stripe documentation) to set up a one-month trial subscription. Add the function of updating to trialing in stripe service
   * The update webhook should automatically change the subscription status to 'trailing.'

2. On the frontend, add buttons for purchasing a subscription and display the user's status as 'Active (Purchased by Points)' instead of 'Trialing'. Or something like that.

3. In the database of user bonuses add a new type of transaction and specify number of points for each type of subscription. Check if user has enough of balance to complete the transaction.
