Fix agent Supabase persistence, streamline nav, add sidebar + workflow page + traders portfolio

[Copilot]

Agents were silently falling back to in-memory/file demo storage on every cold start (serverless = ephemeral), causing "Agent Not Found" on any subsequent lookup. OpenAI responses returned demo-mode strings because .env.local didn't exist in the repo clone.

Supabase schema (supabase-schema.sql)

• All DDL changed to CREATE TABLE IF NOT EXISTS / CREATE INDEX IF NOT EXISTS — idempotent, safe to re-run
• Dropped FK agents.owner_wallet → users(wallet_address) — this was the root cause; FK violations on serverless (user-upsert races a fresh instance) silently triggered demo fallback
• Added explicit ALTER TABLE … DISABLE ROW LEVEL SECURITY for all tables so the service-role key works without manual policy setup
• Action required: apply this SQL in the Supabase SQL editor

Agent create route (app/api/agents/create/route.ts)

• Removed multi-step user-upsert-before-agent pattern; user upsert is now best-effort with debug logging
• Single direct agents.insert path; distinguishes permission-denied vs missing-table vs other errors with clear messages

Navigation

• Navbar reduced to Home / Docs / Devs / About only
• New Sidebar component with SVG icons: Dashboard, Marketplace, Trading, Own Agents, Build Agent, Workflow
• New AppShell client wrapper renders sidebar only on app pages (/dashboard, /marketplace, /trading, /agents, /build, /workflow); root layout updated accordingly

Workflow page (app/workflow/page.tsx) — new

• HTML5 canvas drawing studio: pen, eraser, text, rect/circle/triangle shapes, color palette, stroke-width slider, undo/redo
• File upload for diagram attachments passed to agents
• Task queue planner with sequential Run; 0x402 payment-gate banner fires every 2 completed tasks requiring wallet signature approval
• Wallet-gated: shows connect prompt when no Freighter wallet present

Dashboard traders portfolio (app/dashboard/page.tsx)

• New Traders Portfolio section: summary cards (total profit XLM/USD, paid trades, avg per trade), per-transaction table (agent/strategy, model badge, P&L, Stellar explorer link), live Ably feed strip for incoming trades
