Fix ugig profile endpoint

[okentao]

Summary

• Update the ugig social connector to call GET /api/profile instead of the now-failing /api/users/me endpoint.
• Read the current response shape from data.profile while keeping the old flat shape as a fallback.
• Add a regression test for the live endpoint path and nested profile response.

Verification

• Live ugig API check: /api/users/me returned 404, while /api/profile returned the authenticated profile payload.
• corepack pnpm --filter @profullstack/sh1pt-social-ugig typecheck
• corepack pnpm exec vitest run packages/social/ugig/src/index.test.ts
