Vuetify: page‐title (PageTitleComponent)

General

• Swap <page‐title> for <PageTitleComponent>.
• The default slot has been replaced with an "append" slot, to mirror behaviour of the "prepend" slot.
  • Wrap default slot content with a <template #append></template> tag.
• Adequate spacing around slots is now handled within the component, so margins can be removed when providing slot content.
