Naiyuan Qing b80e952414 feat(views/editor): add AttachmentPreviewModal + Eye entry points ...

In-app preview for non-image attachments. An Eye icon now sits next to
the existing Download button on file cards / readonly file cards / the
standalone AttachmentList. Clicking it opens a full-screen modal that
dispatches by content_type:

  pdf:      <iframe src={download_url}>           — Chromium PDFium
  video/*:  <video controls src={download_url}>   — native controls
  audio/*:  <audio controls src={download_url}>   — native controls
  md:       <ReadonlyContent>                     — full markdown pipeline
  html:     <iframe srcdoc sandbox="">            — fully restricted
  text:     <code class="hljs">                   — lowlight highlight

Media types render directly from the signed CloudFront download_url
(server marks them inline-disposition). Text types fetch through the
new /api/attachments/{id}/content proxy via TanStack Query, wrapped
in useAttachmentPreview() so each entry point owns its own modal
state without depending on a global Provider mount.

Modal sizing: max-w-6xl × min(90vh, 100vh - 2rem) — slightly larger
than create-issue's max-w-4xl since PDF / video need room, but capped
to viewport on small screens. Sub-renderers use h-full to follow the
fixed modal height instead of viewport-relative units.

Images are intentionally NOT touched — the existing ImageLightbox
(extensions/image-view.tsx) already handles them correctly. The new
modal would be churn without user-visible benefit.

Adds i18n keys under attachment.* (en + zh-Hans) and registers
Preview/Download/Upload in the conventions glossary so future
translations stay consistent.
