feat: redesign OIS block — SOFR live data primary, analyst (IL) secondary

Section 1 (SOFR/OIS live, prominent):
- Large current rate → year-end implied + Δbps in bold colored type
- Probability chart across all meetings
- Per-meeting table: date, HOLD/HIKE?/HIKE, prob%, implied rate
- Peak meeting highlighted in amber

Section 2 (G. Dellamotta / InvestingLive, below):
- Analyst year-end bps + next-meeting direction (from IL article)
- Article date shown
- Weekly delta arrows (vs previous article) — lowered bps threshold to 5bps

Add ILCurrent type to CBRatePath to carry analyst absolute values server-side.
