[FEATURE] Disable the store/market view
**Is your feature request related to a problem? Please describe.**
I want to use `bitcart` as a payment-only solution - I will generate an invoice via the API, and show the `pay the invoice view` to the user, but the actual products/services will be defined outside of `bitcart`.
When I create a store, and the user navigates to the payment domain he will see something like this:

Is it possible to show something else on this page (like a custom HTML view), or just disable it altogether?

**Describe the solution you'd like**
Being able to override or disable the `market` view.
Most likely should be possible with some `nginx` config.

**Additional context**
Didn't find anything in the docs.
