feat(console-web): make member lifecycle context strict

[potter-sun]

Summary

• Make Bind present the current member publication as the default contract source instead of service browsing.
• Keep published service ids in the supporting diagnostics area only.
• Make Invoke target selection prefer the selected member identity over stale Bind/Invoke refs.
• Add regression coverage for stale selection continuity and Bind's member-first default surface.

Verification

• npm --prefix apps/aevatar-console-web run test -- --runInBand src/pages/studio/index.test.tsx src/pages/studio/components/bind/StudioMemberBindPanel.test.tsx src/pages/studio/components/StudioMemberInvokePanel.test.tsx
• npm --prefix apps/aevatar-console-web run tsc
• npm --prefix apps/aevatar-console-web run build
• git diff --check

Closes #654
