feat(journey-reader): match spec LR-2 — card layout, interlude, badge, actions; inline note in editor row

JourneyItemCard: restructure from full-<a> to div+card with meta line
(date · von X an Y) and explicit "Brief öffnen →" link; note renders as
mint-border annotation inside the card.

JourneyInterlude: remove ❦ ornament; orange-400 left-border spec classes.

JourneyReader: fix intro classes (dashed border-b); remove bottom author
actions (moved to +page.svelte metabar).

+page.svelte geschichten/[id]: badge above title with spec orange-50 classes;
Bearbeiten/Löschen in metabar right side for isJourney + canBlogWrite.

JourneyItemRow: items-center on main row; drag handle self-center; note
textarea inline in content column (removes border-t section below).

i18n: add journey_item_open, journey_item_meta_from_to to de/en/es.

Tests: update JourneyItemCard + JourneyReader specs to match new structure;
fix datePrecision 'FULL'→'DAY', add receiverCount: 0 to all test fixtures.
