Closes #31

Scope

• Removes the recent heavy simulated-learning UI panels from rendered layouts:
  • Home market brief panel
  • Wallet performance recap, learning insights, trade journal, and simulated activity/reset panel
  • Watchlist compare panel
  • Instrument position summary panel
  • Instrument position sizing coach panel
• Deletes the now-unrendered panel component files to keep the frontend codebase lean.
• Removes unused panel-facing hook exports/imports from use-demo-portfolio so the app module no longer pulls those helper paths into the frontend bundle.
• Updates README and web smoke expectations to match the leaner layout.

Preserved

• README/About product positioning from Clarify simulated trading README and About #30.
• Product/domain docs and ADR/governance docs.
• Simulated trading domain contract, demo trading service, order preview guardrails, virtual ledger behavior, and domain checks.
• Core mock trade flow: buy/sell preview, insufficient-funds guardrail, oversell guardrail, portfolio update, wallet deposit/transfer.

Validation

• npm run typecheck
• npm run check:market-data
• npm run check:simulated-trading
• git diff --check
• npm run export:web
• npm run verify:web-demo

Notes

• This is a normal revert-style PR, not a destructive history reset.
• Local web export page sizes dropped on the affected routes after removing the panels.

Risk / Rollback

• Risk: some recently added educational UI is no longer visible.
• Rollback: revert this PR if the owner decides to selectively reintroduce a smaller redesigned panel later.
