Each account in the switcher wears its own face, and its own renewal warning.

Two accounts could show the same name and avatar: the identity list read a
key stamped onto the account record, and the stamp was taken during the gap
in a wallet switch where the new account is already loaded and saved but the
features haven't re-inited — so the PREVIOUS account's signer was still
answering "who are you". The live signer now re-checks on every read that it
still belongs to the open wallet, not just at init(); and the switcher reads
each account's own persisted login (or its seed's nostr key) instead of the
stamped mirror, so a record stamped wrong before this still lists right.

The Spending renewal warning belonged to the wallet that computed it and
stayed on screen after switching — the old wallet's amount and deadline over
the new wallet's balance, with a 30-minute throttle keeping it there. It now
resets with the ark manager, and the next connect re-decides.
