Root cause of "requires a lot of signs, not just a single one":
inject.ts wired Phantom's own accountChanged provider event to
auto-trigger re-auth, but calling connect() ourselves also fires that
same event -- so a normal silent reconnect raced its own
event-triggered handler, producing two competing "wallet connected"
reports that each independently asked Phantom to sign a fresh nonce.
Removed that event wiring entirely (onWalletEvent, EVENT_CHANNEL) --
inject.ts now only responds to our own explicit calls, never reacts
to unsolicited provider events. Per feedback, account switching isn't
something that should be inferred from a Phantom event anyway; it's
now its own explicit feature: a "Switch account" button in the popup
(nexa:switch-account) that tells the content script to disconnect and
immediately reconnect, so Phantom's connect UI reflects whichever
account is currently active there.
