fix(ui): replace findLast with reverse().find() for WebView compat

findLast() requires Chrome 97+ / Android WebView 97+. Older Android
devices crash with TypeError in pollStatus(), killing all status
updates including the debug log. Use [...arr].reverse().find() which
works everywhere.

Also pass peerMappedAddr in the direct-call connect invoke.
