FIX:When opening or autoloading wallets there should be clear messages about rescanning in progress and wallets' names.

issue-: #259

The "Opening Wallet" popup would now show "Opening Wallet: " instead of just "Opening Wallet". This identifies the specific wallet.

The "Rescanning" popup would show "Rescanning: " or "Rescanning - 0%" if a progress bar is added. Again, this identifies the wallet.

The main window title would include the wallet name after being opened/loaded thanks to the change in WalletView::showNormalIfMinimized().

Other dialogs like Send/Receive coins would also show the wallet name in the title.

So in summary, by appending the wallet name retrieved from WalletModel::getWalletName() to titles and popup messages, it provides clearer feedback to users about which wallet is being loaded and rescanned. No more confusion about which wallet Bitcoin Core is working on.
