Merge bitcoin-core/gui#708: Mask values on Transactions View

4492de1be1 qt: mask values on transactions view (pablomartin4btc)

Pull request description:

  Currently the mask values option (Settings menu->Mask values) hides the wallet balances shown on the Overview page including the recent transactions list from the right panel but it doesn't hide the amounts from the transaction view.

  ![mask values - hiding wallet balances on overview tab but not on transactions tab](https://user-images.githubusercontent.com/110166421/216876325-56a68006-1be0-4b3f-b1e2-a0575c377cf5.gif)

  This enhancement has been mentioned on PR #701 as a [desirable follow-up](https://github.com/bitcoin-core/gui/pull/701#issuecomment-1401350037).

  First approach was to hide the amounts on the  transactions view when mask values option is checked:

  But later on as reviewer **furszy** recommended, I've disabled the Transaction tab directly and switch to the Overview tab if the mask values option is set, check the new screenshots in the [comment below](https://github.com/bitcoin-core/gui/pull/708#issuecomment-1449025828).
