fix(native): a widget tap opens its page every time, also after iOS ended the page

A widget or Live Activity tap reached the UI as Capacitor's appUrlOpen, or
as the launch URL. When iOS had ended the web view's process in the
background, the event went to the old page's listeners and was lost, and
the reloaded page found the same link in getLaunchUrl that it had already
followed once and skipped it: the second tap on the packing widget opened
the start page.

The binary now takes com.liketrek.trek://navigate links itself and hands
them over like a quick action, held until the UI takes it and kept for a
page that is still loading. It reports the feature appLinks, and the UI
only follows the link through Capacitor for binaries without it.
