feat: check OLLAMA_HOST reachability before starting translationv1.6

Non-blocking QThread check hits /api/tags on the resolved ollama host
before launching TranslationWorker. Shows QMessageBox.warning() if
unreachable; proceeds silently if reachable. Adds ollama_host field to
Config with env-var fallback to http://localhost:11434.

-## frontmatter
-### taxonomies
-- [✅] when modifying the frontmatter, the square brackets around the tags or categories lists are not maintained.

 ## Settings
 - [ ] **Font size spinner in UI** — `font_size` is in config but only editable via `~/.config/my-publisher/config.toml`. Add a `QSpinBox` to `SetupDialog` (or a dedicated Settings dialog) so it's changeable without editing the file. Save via `Config.save()`, re-apply with `app.setFont()`. File: `ui/setup_dialog.py`.
