fix: use shared IB status for sidebar state

[damian123]

Summary

• use the shared IB status socket for the sidebar footer badge instead of the price-subscription socket
• keep the Orders footer connected even when the page has no quote subscriptions
• add unit and Playwright regression coverage for the empty Orders-page case

Validation

• npx vitest run --config ../vitest.config.ts web/tests/workspace-shell-sidebar-status.test.tsx
• npx playwright test --config playwright.no-server.config.ts e2e/ws-connection-stability.spec.ts --grep "empty orders page still shows CONNECTED"

[vercel]

@damian123 is attempting to deploy a commit to the Joe McCann's projects Team on Vercel.

A member of the Team first needs to authorize it.

Local validation on head f1c54cb:

• npm run build passed
• npx vitest run --config ../vitest.config.ts web/tests/workspace-shell-sidebar-status.test.tsx passed
• targeted browser regression passed: npx playwright test --config playwright.config.ts e2e/ws-connection-stability.spec.ts --grep "empty orders page still shows CONNECTED"
• touched-surface typecheck grep is clean: npm run typecheck | rg "WorkspaceShell|workspace-shell-sidebar-status|ws-connection-stability" returned no matches

Notes:

• The remaining Vercel failure is the same upstream authorization issue seen on the other PRs, not a branch build failure.
• Ad hoc runs of the full ws-connection-stability.spec.ts file and some standalone status-context tests still hit existing local auth/baseURL and Clerk test-harness issues outside this fix scope.
