Redesign DCF tab — inspector rail layout with HTML canvas

Replaces the flat column layout with a two-column inspector design:
left rail holds four st.slider inputs + "From the filings" reference
panel + Reset/Recompute actions; right canvas renders verdict hero,
projection card (Plotly.js bar chart + cash-flow table), EV bridge,
per-share recon, and cross-check via a single components.v1.html block.

Also fixes primary button text color app-wide by targeting the modern
Streamlit selector (stBaseButton-primary) alongside the legacy one.
