fix: complete directional CouchDB status integration

Keep editor comparison counters compact with their directional CSS classes,
and document selector migration plus an optional CSS animation snippet.

Extend real Obsidian coverage for push comparison with zero transfers,
independent expiry, idle and error states, and the documented snippet.
Prepare the fixture editor before loading the plug-in so the UI scenario
owns its setup order.

+- We can see CouchDB change-feed comparison progress separately for push and pull.
+    - The `⏩↑` and `⏩↓` counts show entries compared in each direction; the upload and download totals remain separate.
+    - Existing CSS snippets which target `livesync-stat-ff` to hide comparison progress need to target both `livesync-stat-ff-push` and `livesync-stat-ff-pull`. See the [status display guide](docs/tips/status-display.md).
