Allow for subscriptions by anonymous users

Which area(s) of Podkrepi.bg are affected? (leave empty if unsure)

No response

Describe the feature you'd like to request

To enhance user experience and increase flexibility, I propose to remove the current restriction that requires users to log in when creating monthly donations. This will enable anonymous users to create subscriptions hassle-free.

Describe the solution you'd like

To ensure accountability, we will send a cancellation link to the user's email, allowing them to make changes as needed. However, in cases where the client's email is unavailable, the payment will still be processed without the option for cancellation.

Describe alternatives you've considered

May be this should be processed AFTER the "new donation flow" is ready and deployed.
