Fixes bugs with Planetcash selector

[mohitb35]

Bugs fixed

1. Planetcash toggled on automatically after disabling - introduced by Enable native payments #447
2. Planetcash switch turned on automatically after updating the amount or editing gift details
3. Resolves issues with paying into planetcash using native payments - payment failure, incorrect amount after visiting from the Add Balance button while on the project page - by making sure to refresh paymentRequest on every change to country, currency, amount.

Also:

1. Resolves an issue of jerky layout seen when Google Pay / Apple Pay buttons were present and amount was refreshed.
2. Enables login to vercel deployments with custom domains (e.g. applepay.pp.eco) without redirecting to the dynamic preview url. This is to be used for testing only, by setting the DISABLE_VERCEL_REDIRECT env to "true"

Functionality works for me as expected.

@mariahosfeld now planetcash payments using native payment methods also work.

Everytime I login and pay with my PlanetCash the donation is done, but I do not see a thank you page, but stay on this page where the payment button is greyed out as following - for paydev.pp.eco one gets correctly redirected to a thank you page:

I don't see this issue, it gets correctly redirected. Could you demonstrate this?

It is a different problem of its own which can be solved separatly:

1. I did a donation before and so reached a page as e.g. https://donate-with-planet-873uy0mu7-planetapp.vercel.app/de?step=thankyou&to=plants-for-life (which step=thankyou as part of the URL)
2. Lazy as I am I reloaded that page in the browser to show the first page again, but the step=thankyou persisted in the URL.
3. Doing a PlanetCash payment then results in staying on this screen probably as the software does not redirect to the thank you page as it already is part of the current URL.
