chore: remove switch wallet page

[theborakompanioni]

Removes the SwitchWalletPage component as it is unfinished and not really needed.
If a user wants so switch a wallet, he can lock or "log out" of the current wallet and choose a different one.

@theborakompanioni looks mostly clean and good , but one leftover from the switchwallet page removal is still present,

the English locale removes wallets.alert_wallet_open and settings.button_switch_wallet, but the same switch-wallet-only keys still exist in the other locale files. Since the page, route, and settings link are gone, can you remove those keys from de, fr, it, pt_BR, ru, zh_Hans, and zh_Hant too?

if you want me i can also commit that changes ?

@theborakompanioni or we can make a follow-up for this what you think?

Yes, we need to cleanup i18n handling from the ground up anyway. But lets first focus on features, unused i18n keys is a concern in the cleanup phase before releasing v2.
