Web dashboard step 4: ratings page and profile editor

Add /dashboard/ratings with the preference-state header, the "How ratings
enter the algorithm" explainer, the Current tab (decayed neighbour weight,
feed credit, prompt/rebuild membership, last-run neighbour usage, inline
rating widget with note) and the paginated, filterable Events tab with
superseded marking.

Add /dashboard/profile: profile.md editor with atomic mode-preserving
writes and profile_versions history plus restore, the parsed preview,
OPML interests by theme, learned adjustments with staleness, the stored
system prompt, and the profile-rebuild job form.

Make profile::MAX_RATINGS_IN_REBUILD and profile::stored_version pub.
