   ### Which Issue(s) This PR Fixes
   
   - Fixes #5796
   
   ### Brief Description
   
   Attempt the hidden-textarea fallback when Clipboard API writes fail. Handle unsupported or throwing fallback operations silently, always remove the temporary textarea, and show the copied indicator only after successful copying.
   
   Add eight component regression tests covering Clipboard API success and failure, fallback success and failure, and temporary-node cleanup. Verify that copied markdown includes answer text and excludes reasoning blocks.
   
   ### How Did You Test This Change?
   
   - `cd web && npm test -- src/pages/ai/components/__tests__/AssistantBubble.test.tsx` — 27 tests passed, including 8 new cases.
   - `cd web && npm run lint` — passed with 0 errors and 10 existing warnings.
   - `cd web && npm run build` — TypeScript compilation and Vite bundling passed; the final license check failed with `license gate: build artifact verification failed: assets/index-DWfsl_c6.js`. The same failure was reproduced on unchanged upstream `12b63f34`.
   - `git diff --check` — passed.
   
   Backend tests and ArchUnit were not run because this change only affects the frontend copy handler and its component tests.
   
   ### Checklist

   - [x] Commit subject follows Conventional Commits (`feat:` / `fix:` / `refactor:` / `chore:` / `docs:` / `perf:`)
   - [x] Tests added or updated for non-trivial changes, test methods named `...Test`
   - [x] New UI text has both Chinese and English entries under `web/src/i18n/` — no new UI text
   - [ ] Architecture constraints stay green (`mvn test` runs the ArchUnit checks)
   - [x] New source files carry the ASF license header — no new source files
   - [x] Documentation touched where behaviour changed (README / `docs/` / in-app help) — existing documented fallback behavior restored
