feat: async chapter-names AI generation with review & apply

- Add POST /api/admin/text-gen/chapter-names/async backend endpoint: fire-and-forget,
  returns job_id immediately (HTTP 202), runs batch generation in background goroutine,
  persists proposed titles in ai_job payload when done
- Register new route in server.go alongside existing SSE endpoint (backward compat)
- Add SvelteKit proxy at /api/admin/text-gen/chapter-names/async
- Add SvelteKit proxy for GET /api/admin/ai-jobs/[id] (job detail with payload)
- Add Review button on ai-jobs page for done chapter-names jobs; inline panel shows
  editable title table (old to new) with Apply All button that POSTs to chapter-names/apply
