refactor(desktop/renderer): centralize platform label and short-name lookup

Move the per-platform translation map out of HomeView/TasksView and the
titleCaseToken fallback out of PublishManagementView into shared helpers
on media-catalog. Single source of truth keeps renderer views consistent
with the binding catalog when new platforms ship.
