fix: date format year

[zChanges]

Angular DatePipe 遵循 CLDR 规范，YYYY 表示周所属年而非日历年。
在 12 月底（如 12-28 ~ 12-31）会被解析为下一年，导致页面年份展示错误。

1-5: Consider adding more context to the changeset description.

The current description "fix: date format year" is minimal. Given the technical nature of this fix (YYYY week-year vs yyyy calendar year in Angular DatePipe CLDR formats), consider expanding the description to help users understand what was fixed when they review the changelog.

+fix: correct date format from YYYY (week-year) to yyyy (calendar year)

+Fixed DateRangePickerPanel footer date format to use 'yyyy-MM-dd' instead of 'YYYY-MM-dd'. 
+The YYYY format represents week-based year in Angular DatePipe CLDR specification, which can 
+cause dates in late December to display the next year incorrectly.
