Check flag if vortex app is opened in Nova dapp browser

[prayagd]

As a vortex user, i should be able to see only Nova wallet option when opened in the Nova browser

Todo

• Check for isNovaWallet flag when the app is opened in the mobile browser, if false or unavailable hide the Nova wallet option
• If the flag is true, Keep the Nova wallet option and hide all other options.
