Add local tag server check, archive on delete, and first-run pin reminder

- Local tag is now clickable - checks if document exists on server by ID
  or filename, and re-links if found
- Delete from server now archives the proxy instead of removing it,
  making it a local-only document that can be re-uploaded
- Added first-run pin reminder banner to help users pin the extension
- Added issue report modal with context sections (extension info, browser
  info, document status, recent errors) and copy to clipboard as Markdown
- Added clearServerFields and attachServerDocument functions to pdf-queue
- Improved local tag styling with hover states and visual feedback
