fix(web-ui): align remote workspace hostname

[bobleer]

Summary

• offset the remote metadata chip by its left inset so the hostname aligns with the workspace title
• preserve the chip padding, truncation, and right-side status dot
• extend the workspace layout regression test with the alignment contract

Testing

• pnpm run type-check:web
• pnpm --dir src/web-ui run test:run src/app/components/NavPanel/sections/workspaces/WorkspaceListSectionLayout.test.ts
• git diff --check
