Add Multiples view; fix Recompute button text color

- Collapse model picker from 4 tabs → 2: DCF and Multiples, persisted
  in session_state["models_view"]
- New Multiples view: summary band, interactive comparison grid (8 math
  rows × 3 methods), sensitivity strip, DCF cross-check, footer
- In-canvas sliders with sector marker + typical-band shading; JS
  recomputes all derived values live without a Streamlit rerun
- Sector medians computed from peer ratios via FMP; falls back to
  reasonable defaults when peer data is unavailable
- DCF intrinsic stored in session_state["dcf_intrinsic"] so the
  cross-check on the Multiples tab reads the live DCF value
- P/Book applicability shows ◐ + warning color for asset-light
  companies instead of the solid ● used for strong-fit methods
- Fix Recompute button text: target inner <p>/<span> with
  color: var(--brass-ink) to override Streamlit's fg-2 default
