[codex] Polish issue composer and long document display (#4420)
## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - Issue comments and documents are the main working surface where
operators and agents collaborate
> - File drops, markdown editing, and long issue descriptions need to
feel predictable because they sit directly in the task execution loop
> - The composer had edge cases around drag targets, attachment
feedback, image drops, and long markdown content crowding the page
> - This pull request polishes the issue composer, hardens markdown
editor regressions, and adds a fold curtain for long issue
descriptions/documents
> - The benefit is a calmer issue detail surface that handles uploads
and long work products without hiding state or breaking layout

## What Changed

- Scoped issue-composer drag/drop behavior so the composer owns file
drops without turning the whole thread into a competing drop target.
- Added clearer attachment upload feedback for non-image files and
image-drop stability coverage.
- Hardened markdown editor and markdown body handling around HTML-like
tag regressions.
- Added `FoldCurtain` and wired it into issue descriptions and issue
documents so long markdown previews can expand/collapse.
- Added Storybook coverage for the fold curtain state.

## Verification

- `pnpm exec vitest run ui/src/components/IssueChatThread.test.tsx
ui/src/components/MarkdownEditor.test.tsx
ui/src/components/MarkdownBody.test.tsx --config ui/vitest.config.ts`
passed: 3 files, 75 tests.
- `git diff --check public-gh/master..pap-2228-editor-composer-polish --
. ':(exclude)ui/storybook-static'` passed.
- Confirmed this PR does not include `pnpm-lock.yaml`.

## Risks

- Low-to-medium risk: this changes user-facing composer/drop behavior
and long markdown display.
- The fold curtain uses DOM measurement and `ResizeObserver`; reviewers
should check browser behavior for very long descriptions and documents.
- No database migrations.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

- OpenAI Codex coding agent based on GPT-5, with shell, git, Paperclip
API, and GitHub CLI tool use in the local Paperclip workspace.

## Checklist
