Fix Team projection catch-up

[potter-sun]

Summary

This PR completes the Console Web Team P0 frontend fixes around canonical Team identity and projection catch-up:

• routes Team detail through /teams/:scopeId/:teamId and treats /teams/:scopeId as a no-team-selected state
• sends Team endpoints through the Studio Hosting API target without stealing runtime member routes
• writes newly-created Teams into the React Query cache, then navigates to canonical Team detail
• handles short-lived projection lag by retrying just-created Team summary/member 404s and showing syncing copy instead of a hard error
• updates Team route, proxy, create, detail, roster, and return-route tests
• updates local console docs/env defaults now that Studio Hosting is composed by Mainnet Host

Why

Team creation is write-side authoritative, while Team list/detail/member reads come from projected read models. In the real Garnet + Elasticsearch setup, the committed Team can be accepted before the read model is visible. Before this PR, the UI could immediately hit 404 or fail to show the created Team in list/detail, which made a successful create look broken.

Validation

• npm --prefix apps/aevatar-console-web run tsc
• npm --prefix apps/aevatar-console-web run jest -- --selectProjects jsdom --runTestsByPath src/pages/teams/detail.test.tsx src/pages/teams/new.test.tsx src/shared/studio/api.test.ts src/shared/navigation/teamRoutes.test.ts src/shared/config/proxyConfig.test.ts src/pages/teams/home.test.tsx src/pages/runs/index.test.tsx --runInBand
• npm --prefix apps/aevatar-console-web run jest -- --selectProjects node --runTestsByPath src/shared/config/proxyConfig.test.ts --runInBand
• git diff --check
• Manual API smoke through http://127.0.0.1:5173:
  • POST /api/scopes/{scopeId}/teams returned 201
  • immediate detail read returned transient 404
  • after ~2s detail/list/members returned 200, and list contained the created Team

Watchman emitted a recrawl warning during Jest, but all targeted suites passed.
