fix: render numeric zero dialog chrome

[nrps9909]

Summary

• render numeric 0 passed through the public ReactNode title and footer props
• keep the dialog's aria-labelledby relationship when the title is zero
• cover the header, footer, and accessible-name wiring with a regression test

Problem

title and footer accept ReactNode, but Panel used truthiness checks to decide whether to render them. As a result, a valid numeric zero was silently dropped. For title={0}, the title element was also omitted and the dialog lost its aria-labelledby reference.

The fix distinguishes numeric zero from other falsy React values while preserving the existing behavior for empty strings, false, null, and undefined.

Validation

• exact-base regression test failed before the implementation and passes afterward
• full Jest suite: 6 suites passed, 61 tests passed, 1 existing skipped, 4 snapshots passed
• TypeScript (tsc --noEmit)
• ESLint (0 errors; one existing file-level unused-disable warning when linting the test directly)
• Prettier check
• git diff --check

I checked current open issues and pull requests. I found no report or PR for numeric-zero title/footer rendering. There are older unrelated PRs that also touch Panel.tsx, but none changes these render conditions.

AI assistance disclosure: Codex was used to trace the render conditions, audit open issues/PR files, run the exact-base regression, and draft this report. The implementation and test are directly reproducible from this branch.

小兔看见标题零，
页脚也把零写清。
Panel 不再漏数字，
ARIA 牵好标题铃，
测试点头跳两蹦。
