fix: hidden categories now auto-switch to default instead of showing error

Browse source 
Two bugs fixed in navigateTo:

1. When a category has visibilityifnocontent: hidden (default) and the
   current page has no variant for it, the renderer now silently switches
   to the default category before fetching. Previously the category stayed
   active (kept visible in the selector via the activeCategory guard),
   the fetch failed, and an error page was shown.

2. The offline message stored in localStorage was shown for any failed
   fetch, not just genuine offline situations. Now gated on !navigator.onLine
   so missing pages always show pagenotfoundmessage instead.
