feat(console): add reviewable AI workflow proposals

[AbigailDeng]

Summary

• Add an Ask AI authoring panel to the canonical Team Member Workflow Studio using the existing contract-backed workflow authoring API.
• Keep generated YAML review-only until explicit application, block stale proposals after human edits, and preserve change requests across retryable failures.
• Preserve separate member, workflow, and published-service identities; this change does not save, publish, bind, or create members implicitly.

Affected paths

• apps/aevatar-console-web/src/pages/team-member-workflow-studio/
• apps/aevatar-console-web/src/locales/

Verification

• pnpm --dir apps/aevatar-console-web exec jest --runInBand --runTestsByPath src/pages/team-member-workflow-studio/index.test.tsx: passed, 87 tests
• pnpm --dir apps/aevatar-console-web exec jest --runInBand --runTestsByPath src/locales/catalog.test.ts src/locales/hardcodedCopyAudit.test.ts: passed
• pnpm --dir apps/aevatar-console-web tsc: passed
• pnpm --dir apps/aevatar-console-web exec biome check <seven affected files>: passed
• bash tools/ci/test_stability_guards.sh: passed, including subordinate guards
• pnpm --dir apps/aevatar-console-web build: passed
• Full frontend and repository test suites were not run under the incremental unit-test policy.

Risks

• bash tools/ci/architecture_guards.sh passed all checks reached before proto lint, then stopped because buf is not installed in the local environment. CI installs buf before running this guard.
• No documentation update was required because this is a localized authoring interaction using existing contracts.

Closes #3116
