Set no backup for all URLs that Initializer uses

[LukasKorba]

All there URLs currently allow backing up to the iCloud (+ all other direct solutions like 2 iPhones close to each other).

    struct URLs {
        let fsBlockDbRoot: URL
        let dataDbURL: URL
        let generalStorageURL: URL
        let spendParamsURL: URL
        let outputParamsURL: URL
    }

When a user buys a new iPhone and restores from the backup, Zashi is restored with all files and folders in these URLs but keys (recovery phrase, birthday) are missing. This is unwanted and we should no backup anything in these URLs.

Use https://developer.apple.com/documentation/foundation/urlresourcevalues

I'm just going through this. I believe that side-by-side phone transfers should be allowed. It is the user intent (in this case myself, but could be any other) that the phone is a "clone" of the other one.
