MechaCat02 b9dd75684e fix(correctness): pagination tiebreakers, dedup race, duration gating (0.87.6)
Three medium correctness fixes:

1. **Pagination ORDER BY missing tiebreakers** — four admin list queries
   sorted by a timestamp or `chapters.number` with no stable secondary
   sort. Add `id` tiebreakers across `repo::admin_view`,
   `repo::admin_audit`, `repo::bookmark`.

2. **`enqueue_pages` NOT EXISTS read-then-insert race** — concurrent
   admin clicks could land duplicate analyze_page jobs. Migration 0031
   adds a partial unique index mirroring 0014; query relies on
   `ON CONFLICT DO NOTHING`.

3. **`record_duration` overwrote a prior done row's duration on a
   non-terminal failed retry of a force-re-analyze.** Gate the call
   on "did this attempt actually write a row?".
