fix(posts): align Index/Calendar routing with Failed→show redirect

- Drop 'failed' from EDITABLE_STATUSES in Index.vue and Calendar.vue
  so failed posts link directly to /show instead of /edit (which now
  redirects).
- Replace remaining 'scheduled'/'publishing' literals in
  PostEditorHeader.vue with the PostStatus enum.
- Include Failed in PostEditorHeader's READONLY_STATUSES to match
  Edit.vue.
- Split PLATFORM_VARIANTS by Platform key (Platform.LinkedInPage and
  Platform.InstagramFacebook were missing; page content types were
  grouped under the wrong personal-LinkedIn key).
