Feature request: Add mint with URL param

[callebtc]

Would be nice if nutstash could add a mint in it's URL param.

Example: https://wallet.nutstash.app/?mint=https%3A%2F%2F8333.space%3A3338.

After such operations (also maybe for token=....-triggered operations), the page should remove the params so the user doesn't get the response every time they reload the page:

// Clear all parameters from URL without refreshing the page
window.history.pushState({}, document.title, "/");

Edit: Maybe it's better to restore the path to window.location.href instead of "/", in case someone hosts nutstash on a non-root path.
