fix: filter out logged-in user from call member pictures in all call states

The Offering, Ended, Connected, and PipConnected call states were showing
the logged-in user's picture alongside other call members. IncomingCall and
Connecting already filtered correctly. Now all states consistently exclude
the current user via `- accountViewModel.account.signer.pubKey`.
