Queue page redesign: compact stats bar replaces summary cards, color-
coded left borders for status scanning, collapsible history with
condensed rows, and a new production schedule timeline view (#823)
showing estimated completion times grouped by hour with filter tabs
and day navigation. i18n keys added for all 7 languages.
Fix plate thumbnails returning 401 in print modal when auth is enabled
(missing stream token). Fix schedule calendar picker opening off-screen
(hidden input positioned with sr-only instead of near the date field).
