feat(console): add Team activity view

[AbigailDeng]

Summary

• add a canonical Team Activity tab backed by the existing Team runtime run window
• share recent-run presentation with Overview while preserving distinct member, workflow, service, and run identities
• add localized filtering, refresh, loading, empty, and read-failure states

Verification

• pnpm exec jest --runInBand --selectProjects jsdom src/shared/navigation/teamRoutes.test.ts --testNamePattern='recognizes the team activity tab without collapsing runtime context' --verbose: passed
• pnpm exec jest --runInBand --selectProjects jsdom src/pages/teams/detail.test.tsx --testNamePattern='loads, filters, and refreshes team-scoped activity from a direct route' --verbose: passed
• pnpm tsc: passed
• pnpm exec biome lint src/locales/en-US.ts src/locales/zh-CN.ts src/pages/teams/components/TeamRecentRunsList.tsx src/pages/teams/detail.test.tsx src/pages/teams/detail.tsx src/pages/teams/tabs/TeamActivityTab.tsx src/pages/teams/tabs/TeamOverviewTab.tsx src/shared/navigation/teamRoutes.test.ts src/shared/navigation/teamRoutes.ts: passed
• bash tools/ci/test_stability_guards.sh: passed
• pnpm build: passed
• full frontend and repository test suites were not run under the incremental test policy

Risks

• Desktop, tablet, and mobile browser inspection remains a review gap because both available local browser profiles were redirected by the OAuth gate; no session was injected and no login was attempted.

Affected paths

• apps/aevatar-console-web/src/pages/teams/
• apps/aevatar-console-web/src/shared/navigation/teamRoutes.ts
• apps/aevatar-console-web/src/locales/

Documentation

• No documentation change; the existing Team runtime read-model contract is unchanged.

Closes #3120
