fix: mobile public share — remove map tab (#828), cap timeline width (#827), wire entry click (#826)

- #828: exclude 'map' from availableViews on mobile; MobileMapTimeline already
  shows combined map+timeline so the standalone map tab is redundant
- #827: cap timeline feed column at xl:max-w-[50%] on ≥1280px viewports so the
  map aside is not dwarfed on wide monitors; applies to both desktop two-column
  layouts (JourneyPublicPage)
- #826: wire MobileMapTimeline onEntryClick to setViewingEntry; render
  MobileEntryView with readOnly + public photo URL builder so photos load via
  the share token endpoint; add publicPhotoUrl prop to MobileEntryView so
  photo URLs are routable for both authenticated and public-share contexts
