feat: hot topics daily rotation — 30+ topic pool, seeded shuffle, next-refresh countdown
- Expanded research pool to 9 topics (was 3), evergreen to 12 (was 3) - Conference topics: added Photonics West, CIOE, NFOEC follow-up, year-end review - Standards topics: 3 rotating variants (IEEE tracker, SFF-8024 registry, OIF CEI-112G) - seededShuffle(): day-of-year as seed — stable within the day, different every day - API response adds refreshes_at (next midnight UTC) for frontend countdown - Dashboard subtitle shows 'rotates daily · next refresh in Xh' - Hot topic cards now pass full title + angle into generateBlog() correctly
