Merge #16106: gui: Sort wallets in open wallet menu

fa90fe6 refactor: Rename getWallets to getOpenWallets in WalletController (João Barbosa)
224eb95 gui: Sort wallets in open wallet menu (João Barbosa)

Pull request description:

  Ensure wallets are sorted by name in the open wallet menu. This also improves the change done in #15957, since it avoids a second call to `listWalletDir`.
