lashman 4b939f044a Add AppImageHub.com OCS API as primary catalog source ...

Integrate the Pling/OCS REST API (appimagehub.com) as the primary catalog
source with richer metadata than the existing appimage.github.io feed.

Backend:
- Add OCS API fetch with pagination, lenient JSON deserializers for loosely
  typed numeric fields, and non-AppImage file filtering (.dmg, .exe, etc.)
- Database migration v17 adds OCS-specific columns (ocs_id, downloads, score,
  typename, personid, description, summary, version, tags, etc.)
- Deduplicate secondary source apps against OCS entries
- Shrink OCS CDN icon URLs from 770x540 to 100x100 for faster loading
- Clear stale screenshot and icon caches on sync
- Extract GitHub repo links from OCS HTML descriptions
- Add fetch_ocs_download_files() to get all version files for an app
- Resolve fresh JWT download URLs per slot at install time

Detail page:
- Fetch OCS download files on page open and populate install SplitButton
  with version dropdown (newest first, filtered for AppImage only)
- Show OCS metadata: downloads, score, author, typename, tags, comments,
  created/updated dates, architecture, filename, file size, MD5
- Prefer ocs_description (full HTML with features/changelog) over short
  summary for the About section
- Add html_to_description() to preserve formatting (lists, paragraphs)
- Remove redundant Download link from Links section
- Escape ampersands in Pango markup subtitles (categories, typename, tags)

Catalog view:
- OCS source syncs first as primary, appimage.github.io as secondary
- Featured apps consider OCS download counts alongside GitHub stars

UI:
- Add pulldown-cmark for GitHub README markdown rendering in detail pages
- Add build_markdown_view() widget for rendered markdown content
