feat(admin): category SEO fields, Templates admin, safe project PATCH

- categories/tags admin forms: add meta title/description/keywords, bot-follow,
  sort, is_active (backend already supported these)
- new Templates admin (/admin/templates): container CRUD with description,
  keywords, publishing, premium, primary mode, category/tag assignment, plus
  editable per-variant aspect & resolution
- content-svc: PATCH /v1/projects/{id} partial update so aspect/resolution edits
  never wipe render/colour data (SharedColorsSvg, RenderAepComp, Folder)
- admin resource proxy: add PATCH passthrough
