Add "Sign into another account" — switch identities without logging out.

The only way to move between identities (e.g. Adam via a Nostr remote signer and passkeyguy via passkey) was logout → forget all data → sign in again, which wipes every account. But the machinery to hold several accounts at once already exists: enterWallet/addOrGetAccount ADD an account (they don't replace), the unlock screen carries the sign-in doors (Nostr/passkey/Google via unlockExtra) plus a fromWallet Back button, activateAccount cleanly tears down and re-inits per-account nostr-login state, and the Accounts screen already switches between saved accounts. The nostr-login handoff even saves its session AFTER activating the new account, so each identity's signer state lands under its own namespace and resumes silently (persisted passkey sk / bunker session).

The missing piece was a non-destructive entry point. Added a "Sign into another account" button on the Accounts screen that opens the unlock screen in additive mode (ui.fromWallet), so signing in adds the identity alongside the current one — then switching is just tapping a row on the Accounts screen (reached via the balance card's Accounts button), no logout, no data loss.
