Fix Studio Team member route context

[potter-sun]

What changed

• Preserve Team context when Console Web opens Studio from Team list/detail pages.
• Keep backend Team member identity as the primary Studio route identity when it exists.
• Use workflow/script identities as focus so asset deep links do not replace the Team member context.
• Preserve teamId through Studio bind/invoke/member switching and return links.
• Fix a mobile Team page layout issue found during design review: document-mode pages no longer lose 80px of horizontal content width on small screens, and Team roster view toggles now meet the 44px touch target.

Why

Issue #585 needs Studio links to stay scoped to the selected Team and member. Without this, users can enter Studio from a Team surface and lose the Team/member context, which makes the route look correct at the Scope level but wrong at the product level.

Impact

• Console Web only.
• No backend changes.
• No CLI frontend changes.
• Team/Studio route behavior becomes consistent across Team home, Team detail, asset links, Studio lifecycle transitions, and return navigation.

Validation

• npm --prefix apps/aevatar-console-web run tsc
• npm --prefix apps/aevatar-console-web run jest -- --selectProjects jsdom --runTestsByPath src/pages/teams/home.test.tsx src/pages/teams/detail.test.tsx src/pages/studio/index.test.tsx src/shared/studio/navigation.test.ts --runInBand
• npm --prefix apps/aevatar-console-web run jest -- --runTestsByPath src/shared/studio/navigation.test.ts --runInBand
• npm --prefix apps/aevatar-console-web run jest -- --selectProjects jsdom --runTestsByPath src/pages/teams/home.test.tsx src/pages/teams/detail.test.tsx --runInBand
• git diff --check
• /design-review browser screenshot verification for Team home/detail mobile layout

Closes #585
