fix: preserve pending range selection on hover

[zombieJ]

Summary

• keep a modified RangePicker endpoint selected while its confirmation is pending
• render the hovered cell with an independent hover state while retaining the input preview
• preserve existing range and preset previews and add regression coverage

Validation

• ut test --runInBand: 15 suites passed, 469 tests passed, 2 skipped
• ut lint:tsc
• ut lint: 0 errors, 16 existing hook warnings
• focused Prettier check and git diff --check

Fixes ant-design/ant-design#59070.

AI assistance disclosure: Codex was used to trace the hover state flow, add the regression test, implement the fix, run validation, and draft this description.

Summary by CodeRabbit

• Bug 修复
  • 修复 RangePicker 启用时间选择时，选择开始日期后悬停结束日期，待确认的选中状态显示不正确的问题。
  • 优化范围选择中的悬停反馈：已有另一端日期时优先显示完整范围悬停效果。
  • 悬停结束日期时，开始日期与悬停日期的高亮样式及输入框预览值现可正确更新。
• 测试
  • 增加了针对日期时间范围选择及悬停状态的覆盖测试。

Walkthrough

RangePicker 现在保留待确认的选中日期，并单独显示悬停日期。范围模式会根据另一字段的值选择弱悬停或完整范围悬停。测试覆盖 showTime、确认和非确认场景。

Changes

范围选择悬停状态

Layer / File(s)	Summary
选择面板悬停值 src/PickerInput/RangePicker.tsx	当另一字段没有值时，RangePicker 使用当前字段的单个悬停值。否则使用完整的 hoverValues 范围。
渲染并验证悬停状态 src/PickerInput/Popup/PopupPanel.tsx, tests/range.spec.tsx	PopupPanel 在范围模式下单独传递 hoverRangeValue。测试验证待确认选中状态和已确认范围悬停样式。

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 8b853

RangePicker preserves a pending selected endpoint while rendering the hovered date independently, and retains full-range hover styling once an endpoint is confirmed. The covered behavior is ready to merge.

Poem

小兔轻点悬停键，
选中日期仍闪亮。
范围端点分明现，
时间面板不迷航。
测试铃声叮当响。
