feat(kol): expand variable schema and polish KOL UI

- Add length/range limits to KOL variable definitions: max_length and
  default_value for input/textarea, min_value/max_value/default_number
  for number. Backend validates and normalizes; frontend renders limit
  inputs in KolVariableConfig and applies limits at runtime in
  KolDynamicForm.
- Sort workspace cards by most recent prompt/package update, falling
  back to granted_at. Adds updated_at to KolWorkspaceCard.
- Polish TemplatesView, WorkspaceView, and KOL package management UI;
  route create/update/publish/archive/delete toasts through i18n and
  expand package form copy and status labels.
- Remove stale KnowledgeView.vue.patch.
