ci: add E2E tests to release workflow

- Add E2E converter tests in Docker container (verify-image job)
  - Inkscape: SVG → PNG
  - Pandoc: Markdown → HTML
  - LibreOffice: TXT → PDF
  - FFmpeg: Audio generation
  - ImageMagick: PNG → JPEG
  - API healthcheck endpoint

- Add cleanup step for verification containers
- Update verification summary to include E2E results
- Install pandoc and imagemagick in run-bun-test workflow for E2E tests
