feat: replace per-author cap with interleaving to avoid dropping posts in feed and home

The old `diversify_by_author` capped each author to 2 posts per page, silently dropping excess rows. The new `interleave_by_author` reorders the full result set so no two consecutive posts share an author, preserving every post while breaking up same-author runs. `paginate_diverse` loses its `max_per_author` and `pool` parameters; the home route now fetches exactly 6 rows and interleaves them instead of over-fetching 50 and capping. Tests are rewritten to verify interleaving behavior and per-author chronological order preservation.
