fix: fix: wallet connector panel not rendering at standard viewports — blocks all user funnels (#1156)

Root cause: the test wallet provider's eth_accounts and getProviderState
always returned the account address regardless of connection state. This
caused wagmi to auto-connect via EIP-6963 provider discovery, skipping
the 'disconnected' status entirely. As a result, .connect-button--disconnected
never rendered and .connectors-element was never shown.

Changes:
- wallet-provider: eth_accounts returns [] when not connected (EIP-1193 compliant)
- wallet-provider: getProviderState returns empty accounts when not connected
- All wallet connection helpers: handle auto-reconnect case, increase timeout
  for wagmi to settle into disconnected state (5s → 10s)
