Route Create Team to Studio member creation

[potter-sun]

Summary

• Route the Teams home Create Team CTA directly into Studio with a typed create-member intent.
• Auto-open the existing Studio create-member flow for that intent without creating a backend draft or team fact.
• Keep /teams/new as a hidden legacy recovery page and update copy/tests to describe initial member draft recovery.
• Collapse the console shell navigation by default for this focused Studio entry.

Why

The previous Create Team page implied a persisted Team was being created, while the current product flow actually starts team construction by creating the first Studio member. This makes the route and copy honest without introducing backend team semantics.

Closes #319

Validation

• npm --prefix apps/aevatar-console-web test -- --runInBand apps/aevatar-console-web/src/pages/teams/new.test.tsx apps/aevatar-console-web/src/pages/teams/home.test.tsx apps/aevatar-console-web/src/pages/studio/index.test.tsx apps/aevatar-console-web/src/app.layout.test.ts apps/aevatar-console-web/src/shared/studio/navigation.test.ts apps/aevatar-console-web/src/routesConfig.test.ts apps/aevatar-console-web/src/shared/navigation/navigationMenuSelection.test.ts
• npm --prefix apps/aevatar-console-web run tsc
• bash tools/ci/test_stability_guards.sh
• git diff --check

Note

npm --prefix apps/aevatar-console-web run biome:lint still reports existing unrelated lint debt in the console web package.

Two actionable issues stood out in this flow: scope should be preserved when entering create-member from Teams, and the menu-collapse behavior likely needs a controlled state instead of relying on defaultCollapsed. Leaving both inline for easier follow-up.
