feat(post-form): U3 — auth-aware feed collection; drafts owner-only

Owner-aware draft visibility (R5, KTD7/KTD8) on trip.html.twig and home.html.twig
(active-trip branch):
- Compute owner_can_edit = authenticated AND username == site.owner_username AND
  (this is the active trip). The super-admin tester authenticates too, so the gate
  is owner identity, not mere login.
- The feed list (all_items) uses an owner-aware journal collection: owner sees
  drafts, everyone else (and every non-active-trip view) sees published only.
- journal_entries stays published-only — it feeds stats/counts. map_entries now
  filters on item.page.published, so drafts get a feed card but no marker and no
  stat contribution.
- Thread owner_can_edit into trip-feed-col (defaults false) for the U4 controls.
Between-trips home grid stays published-only. Stories untouched (journal drafts only).

Verified on the container: draft entry with coords shows in the owner's feed but
not the map or count; absent entirely for anonymous (V4).
