feat: AI assistant v2, prop firms page, public performance profiles

[gehlotmanthan]

Summary

• Stream C — AI Strategy Assistant v2: Upgraded from raw fetch stream to useChat (@ai-sdk/react). Route now returns toUIMessageStreamResponse(). New StrategyCodeBlock component parses Pine Script v5 and Webhook JSON from the AI response into separate copy-button blocks. Persistent chat history within session.
• Stream D — Prop Firm Discovery: New /prop-firms dashboard page listing Apex, Topstep, FTMO, E8 Markets, and Alpaca paper with compatibility badges, funding details, and profit split. Added to sidebar nav with Trophy icon.
• Stream E — Public Performance Profiles: Migration 028 adds public_profile_enabled, profile_slug, public_display_name, public_bio to profiles. New public page at /p/[username] shows published strategies + acquisition CTA. Settings page gets a PublicProfileForm toggle to opt in and set username.

Test Plan

• Run npx vitest run — 74 tests pass, no new failures
• AI assistant: open a strategy → AI Strategy Assistant → type a description → verify Pine Script and JSON blocks appear with copy buttons
• Prop firms: navigate to /prop-firms → verify 5 firms listed, Apex/Topstep/Alpaca show green Compatible badge
• Public profile: go to Settings → enable public profile, set a slug → visit /p/<slug> → verify profile page loads with CTA
• Run migration 028 in Supabase SQL editor before deploying
• Set STRIPE_SECRET_KEY and related env vars before enabling billing (Stream A, not in this PR)
