feat: redesign templates page with tree sidebar + list layout

Replace the old 3-column layout (form + table + filters) with:
- Left sidebar: tree menu grouped by contract type, template category,
  and industry, with count badges and search
- Right panel: clean list view with inline actions (edit, publish,
  delete, version history)
- Create/edit moved to Drawer
- Version history moved to separate Drawer
